The Singapore MRT is one of the most wheelchair accessible train systems in the world.
There is at least one barrier-free entrance in every train station as well as a fare gate wide enough for wheelchairs
Elevators are easy to find, near the accessible train carriage, and fairly big
While wheelchair users can use any carriage, wheelchair-accessible train carriages have two large wheelchair spaces per train. To locate them, look for wheelchair indicators on the platform floor or screen doors.
There is practically NO GAP between the train and the platfom
The stations have walls preventing riders from falling onto the track
Tactile blocks are available for those with visual impairments
Mobility scooters are welcome on the trains
Buses are also very accessible but not all routes are accessible yet (currently 80% are, 100% accessible by 2020). However, the major tourist routes are accessible. Drivers are very responsive to gestures if you want to hail the bus. After stopping, they flip out a ramp from the middle doors to drive up (sometimes readjusting the bus’ position is necessary). There is a large area for wheelchairs and mobility scooters.
