### The transfer position shall be

### The transfer position shall be

### A horizontal handrail shall be 

### provided at each side of the toilet seat. The handrail on the wheelchair accessible side shall extend to the leading edge of the toilet seat and shall be hinged in such a way so as to enable an unobstructed transfer for the wheelchair user to and from the toilet seat. 6’’ 13.8’’

### There shall be a minimum 

### clear space of 27.6’’ from the front edge of the toilet seat and over its entire width.

The clear space can be used as maneuvering space and/or as part of a transfer 

### position.

### The toilet compartment shall allow the unobstructed

LIRR toilet 18.9
NJT toilet 21.3 Amtrak Acela Express toilet 24.1

- Turning circle 19.1 Toilet w/ lateral transfer & turning circle 25.2CONCLUSIONS



### • The CFR does not establish a relationship between the minimum clear floor area and other toilet fixtures.

• The minimum clear floor area is rectangular; square corners may lead to unused/unusable space.



### • ISO 7193 requirements cover wheelchairs usable by 85% of disabled people. • The wheelchair size defined in the CFR is almost identical to the occupied wheelchair defined under ISO 7193.

• The CFR requires grab bars to be installed on walls; they should be located using the water 

### closet as the point of reference.

24 Rail Vehicules Access Advisory Committee

– Toilet Module FootprintCONCLUSIONS



### • A lateral transfer from the wheelchair to the water closet seems to be the preferred transfer method.

• A turning circle inside the 

### toilet module makes it easier for the wheelchair occupant to access all toilet amenities (sink, hand 

### dryer, soap, door latch, intercom, etc.). • Toilet modules large enough to accommodate a turning circle and transfer position are slightly larger than the Amtrak Acela Express accessible toilet module.

• A diagonal transfer position can lead to a smaller toilet 

### module footprint.
