washing/bathing, as set out in 4.1.2
4 Water equipment
4.1 Water supply and storage
4.1.1 Fresh water supply

The tanks and the filling and emptying pipes shall be made of material that will not deteriorate and, in

particular, material used shall not be corrosive or toxic.
Materials used shall be suitable for potable water.

NOTE Materials are certified to nationally agreed standards of materials for potable water, such as DVGW or ACS.

The combination of differing materials should be analysed to avoid electrolytic corrosion. Consideration

should be given to the choice of material so that it does not reduce the water quality. It is normally a

compromise between the best quality and durability.
---------------------- Page: 7 ----------------------
oSIST prEN 17863:2022
prEN 17863:2022 (E)

The design life of a railway vehicle is normally 25 - 40 years; consideration should be given to the ability

of materials to sustain this service life or the design of the system should take account of the need to

change components.

Water tanks and pipes shall be provided with a drainage system designed to ensure complete emptying

and efficient rinsing and meet the requirements of EN 16362:2013 Clause 4.1.4

The water pipe system shall be drainable for all pipes. System shall automatically drain the pipe system

if the internal toilet temperature falls below 4° C. It is permitted for trace heating to be fitted to toilet

pipes to prevent freezing as an alternative to drainage.

From the test described in EN 16362:2013, 4.1.1.1 if the car body cannot withstand 12 h at −10° C the

water pipe system shall be drained if the coach is stabled without shore supply. This drainage shall either

be automatic, or an instruction is provided that drainage should be carried out – see 6.2. As design

guidance it is preferable to also be able to drain pipework manually where this is automatic.

The freshwater system and its surroundings shall incorporate design features to prevent, or detect and

report, water leaking into the car body. It is permissible for the design to permit water onto the toilet

floor area, but it shall prevent this from spreading to the passenger compartment/vestibule/car body

unless this is a deliberately defined area.
4.1.2 Water intended for human consumption

Water intended for use for making hot drinks shall be heated to a minimum of 80° C and:

a) be water intended for drinking

b) the water shall be sterilized immediately before use by ultraviolet radiation or micro filtration

c) supplied directly from freshwater containers/bottles.
Water intended for use for drinking water shall:
a) be water intended for drinking
b) provide freshwater containers/bottles.

Water intended for washing and showering shall be potable or meet the requirements of 4.1.3.

4.1.3 Recycled water

Treated black water, treated purple water and untreated grey water shall only be used for toilet flushing

if it is liquid only. The appearance and odour should be treated to be acceptable for the user.

Treated grey water is permitted to be reused for handwashing if it meets potable water requirements.

4.1.4 Storage tank

The capacity of freshwater storage tanks shall be calculated using parameters shown in

EN 16922:2017+A1:2019 5.2.2 and 5.2.5. The size of the freshwater tank is a compromise between the

anticipated daily usage and preservation of the stored water quality. As guidance, to retain the optimal

hygienic quality of the potable water the usable volume of the freshwater storage tank should ideally

store only two/three day's water supply.
---------------------- Page: 8 ----------------------
oSIST prEN 17863:2022
prEN 17863:2022 (E)

The freshwater tank shall be capable of draining manually without any electrical or pneumatic supply.

The draining flow of the freshwater tank shall be compliant with EN 16362:2013 Clause 4.1.4. As design

guidance it is preferable for the driver of multiple units to be able to drain all freshwater tanks from the

driving position.

Fresh water tanks shall have a hatch for inspecting and cleaning the freshwater tanks. The access hatch

2 2

shall have a minimum size of 20 000 mm , but it should be 40 000 mm where this is possible. The access

hatch shall be accessible without draining more than 50 % of the capacity of the fresh water. As design

guidance the least water to be drained is preferable. The access hatch of the freshwater tank shall be

accessible without removing any other parts (excluding insulation materials). When the freshwater tank

is located inside a cabinet or behind a panel, it is permitted to have access to the hatch of the freshwater

tank by opening a door or other hatch.

The capacity of retention tanks shall be calculated using parameters shown in EN 16922:2017+A1:2019

5.2.2 and 5.2.5. As design guidance the recommendation is that it should be tailored to four day's

predicted amount, given by calculation according to EN 16922:2017+A.1:2019, however this depends on

the intended use of the train as the tanks size is a compromise between vehicle mass and operational

needs.

The design of the system should consider the need for water level indication in on-board storage tanks.

Some previously used examples are described in EN 16362:2013, Annex A. The indication should

consider the necessity for the accuracy of the display, this should consider whether it is necessary to show

the precise fluid volume or an indication of tank level.

There is also the potential to include the tank levels into the remote condition monitoring systems so that

enroute servicing points could have advanced warning of location of tanks needing replenishment.

If a train control and management system (TCMS) is available, the message “freshwater tank empty” shall

be reported in the TCMS. As design guidance, if a TCMS is available, the continuous actual level in the

freshwater tank should be reported to the TCMS. If more information is available, for example retention

tank reached 95 %, this should also be reported to the TCMS.
4.2 Wash hand basin
4.2.1 Dimensions

The wash basin shall be built of material resistant to corrosion, staining and abrasion.

The wash basin shall be sufficient size for comfortable washing of hands and shall be no smaller than

220 mm wide and 160 mm from front to back. The shape of the wash basin should contain the normal

use with no overflow of water during acceleration and braking of up to 0,1 g if the actual design

accelerations of the train are not higher.

The sink drain shall be situated at the lowest point of the sink bowl; it shall be always open to discharge

(i.e. not be fitted with a plug).

The sink drain shall be fitted with a perforated plate, or similar device, to prevent large objects entering

the discharge pipe - no object greater than 4 mm diameter shall be able to pass through the drain and

items smaller than 3 mm diameter shall pass through. The design of the drain shall permit the draining

of 1 l of water in 10 s.

The tap discharge point shall be a minimum of 95 mm above the rim of the wash basin and positioned to

permit the washing of hands under running water.

The design of the tap discharge shall minimize the likelihood of splashing with water during use. As an

example, this could be proven with no obstruction and then with the presence of hands simulated by a

100 mm diameter disc placed 50 mm beneath the water tap outlet and check that no water is splashed

outside the wash basin.
---------------------- Page: 9 ----------------------
oSIST prEN 17863:2022
prEN 17863:2022 (E)

To prevent vandalism damage, the wash bowl unit and its fixing shall withstand a static force of 1000 N,

applied across a 55mm diameter area, without damage or permanent deformation.
4.2.2 Water supply/heating (& legionella)

The volume of water supplied shall be a minimum of 180 mL in 7 s. As design guidance 250 mL is a

preferred volume to achieve acceptable washing of hands.

Where the hand wash water supply is heated the water at a sink shall either be available at a temperature

of minimum 13° C and maximum 22° C (or ambient external temperature) without manual control by

passenger while the train or the coach is in passenger service, or a mixer tap fitted.

If a mixer tap is fitted, the warm water supply should be heated at a temperature of minimum 60° C in

order to prevent the supply water against Legionella.

The design of the mixer tap shall prevent scolding water, the maximum temperature at the delivery point

shall not exceed 43° C.

NOTE On some designs of mixer tap there is a special design feature for disinfection which allows greater

temperature, but this is completed under controlled conditions.

Due to the possibility of bacteria growth, water supply tanks shall be designed to enable the tank and

pipework to be flushed when required.

If a water tap is turned on by a proximity sensor this shall be indicated by the sign shown A.13.

4.2.3 Soap supply

Washing facilities shall be fitted with a liquid/foam soap dispenser or be supplied with solid soap bars.

If a soap dispenser is fitted the tank shall be easily accessible for stocking by servicing staff but protected

from general public access to the tank by, for example, a Berne key.

The soap dispenser shall be fitted directly above the hand wash basin, so that any spillage is directly into

the basin and labelled - see example A.10.
The volume of the liquid soap dispenser shall be a minimum of 0,75 l.

The soap dispenser shall be easy to fill and clean. The design shall consider that any spillage during the

filling process does not run into inaccessible spaces. Components that are difficult to clean shall not be

located beneath or in the vicinity of the soap filling opening to prevent spillage causing additional

cleaning activity.

For a liquid soap dispenser, it shall be possible to refill by pouring soap from above from a separate

container without removing the soap dispenser tank and without spillage. This is fulfilled if there is an

unobstructed free space of 80 mm, as a minimum, above the soap dispenser tank.

As design guidance the soap dispenser outlet is best placed directly above the sink such that spillage of

soap in use falls into the sink.
4.2.4 Hand sanitiser
It is permissible to fit a sanitiser dispenser.

If a sanitiser dispenser is fitted the tank shall be easily accessible for stocking by servicing staff but

protected from general public access to the tank by, for example, a Berne key.

For a sanitiser dispenser, except as shown below, it shall be possible to refill by pouring sanitiser from

above from a separate container without removing the sanitiser tank and without spillage. This is fulfilled

if there is an unobstructed free space of 80 mm, as a minimum, above the sanitiser tank. Where the

sanitiser used is flammable, additional care in the design shall be taken to ensure that there is little chance

of spillage, or the filling of the tank shall be completed remote from the coach.

---------------------- Page: 10 ----------------------
oSIST prEN 17863:2022
prEN 17863:2022 (E)

Components that are difficult to clean shall not be located beneath or in the vicinity of the sanitiser tank

opening to prevent spillage causing additional cleaning activity.

As design guidance the sanitiser outlet is best placed directly above the sink such that spillage of sanitiser

in use falls into the sink.
4.2.5 Hand dryer/towel

It is permitted to fit either a hand dryer or paper dispenser (or both). It is recommended that an air dryer

is fitted for cleanliness, ecological and sustainability reasons, prevent increased litter, fire risk, restocking

maintenance requirement and to prevent hand towels blocking the toilet flush system. Hand towels

should only be used where considered necessary, It is preferable to fit an electric hand dryer to reduce

waste and help the environment.

The outlet of the dryer or dispenser shall be a maximum of 1200 mm above floor level. The dispenser

shall meet the reach range as shown in EN 16585-1:2017 Annex B.

The dryer or dispenser shall be easily visible or indicated by a pictogram as given in A.3.

Electric hand dryers shall:
a) be contained in splash proof casing.
b) only operate for a specific period and then shall automatically stop.

c) heating elements automatically de-energize when the blower motor is not operating, or the outlet

blocked.
d) de-energize when the temperature exceeds 62 °C.
e) be tamperproof by passengers but maintainable by staff.

Where an electric hand dryer is not fitted a paper towel dispenser shall be fitted. It is also permissible to

fit both.

If the toilet is equipped with a hand paper dispenser, it shall dispense paper on the basis of a single sheet

of paper at a time, to prevent overconsumption and potential blocking of the toilet bowl as a result of

misuse.

Paper dispenser shall accommodate stored paper of 265 mm by 100 mm. The height should be a

minimum of 400 mm. The values quoted here are the largest which will ensure compatibility between

servicing points; it is possible to fit smaller size dispensers where the size of paper to replenish the stock

is controlled. The type of paper provided in the dispenser shall either be compatible with the toilet flush

system or a notice shall be prominently displayed to not put paper towel in the toilet bowl as shown in

A.2.

Where a paper towel dispenser is fitted, the position shall permit the easy refilling of the paper. Where a

paper towel dispenser is fitted, passengers should be discouraged from gaining access to the paper

container by the fitting of locks. It is normal practice to gain access to consumable products by use of a

square key. The hand towel dispenser shall have a pictogram, as shown in A.4, on the inside to describe

the orientation and folded state requirements of the hand towels. The stock level of paper shall be clear

to servicing staff.
Wherever hand towels are used a waste bin shall be provided, see 5.3.7.

oSIST prEN 17863:2022
prEN 17863:2022 (E)
4.3 Shower
4.3.1 Dimensions

The shower shall permit a standing person to wash hair and body. The floor shall be non-slip and direct

water to a drain.
A shelf for soap shall be provided.
The shower shall be fitted with a grab hand rail.
4.3.2 Water supply/heating (& legionella)

Water supply for showers shall be fitted with mixer taps. The design of the mixer tap shall prevent

scolding water and the maximum temperature at the delivery point shall not exceed 43° C.

The hot water temperature, before the mixer tap, shall be a minimum of 60 °C to discourage legionella.

4.4 Waste water (from sink and shower)
4.4.1 Sink
Grey water from the hand wash sink shall be directed to:
a) to its own retention tank

b) the toilet retention tank via a non-return valve that will permit the flow in one direction only, to avoid

pathogenic germs rising back into the wash basin.

c) straight to the track or via an intermediate tank or non-return valve to avoid pressure pulses in

tunnels.

The grey water system shall be designed to prevent the wheel/rail noise from outside the coach entering

the toilet cubicle through the drain.

For gravity operated grey water systems from the handbasin, the cross section of the grey water outlet

(hoses and piping) shall be at least 800 mm . The shape shall be circular or elliptical.

4.4.2 Shower
The purple water from the shower shall be directed to:
a) to its own retention tank

b) the toilet retention tank via a non-return valve that will permit the flow in one direction only, to avoid

pathogenic germs rising back into the wash basin.

For gravity operated purple water systems from the shower, the cross section of the purple water outlet

(hoses and piping) shall be at least 1100 mm . The shape shall be circular or elliptical.

5 Toilet
5.1 Provision of toilet
5.1.1 Fitment

The requirement for provision and number of toilets on the train shall be taken at the design stage. This

is normally done at the specification stage of design and in cooperation between the manufacturer and

the intended operators.
---------------------- Page: 12 ----------------------
oSIST prEN 17863:2022
prEN 17863:2022 (E)

Noting that the provision of toilets at stations should be considered as part of the overall system solution,

the guidance to be cognisant of frequency of service and likely to be different for:

a) Long distance inter-city journey times > 4 h
b) Commuter / regional trains journey times 1 – 2 h
c) Light rail / metro journey times < 90 min

Consideration should be given to the position of the toilet within the train, the potential walking distance

to a toilet should be considered. As guidance to calculate requirement for, and number, of toilets:

i) The provision of toilet facilities is expected for long-distance inter-city trains. This should be a

minimum of the same number of toilets as coaches. This could be increased to two toilets per coach

if the seating exceeds 50.

ii) The provision of toilet facilities is recommended for commuter/regional trains, as a minimum one

toilet per two coach trainset, two toilets per three coach trainsets, three toilets per four coach

trainset, four toilets up to six coach trainset, five toilets up to eight coach trainsets and six toilets for

any trainset above eight coaches. As a minimum one toilet per three coach train. This could be

increased for coaches intended for longer distances or increased seating.

iii) The provision of toilet facilities for light rail or metro type trains is not normal practice, but toilets

can of course be fitted. It is permissible to fit a ‘low use toilet’ which have less facilities a
