Unlike those at the airport, the travellators in MRT stations are on a flat surface. They just help you get from point A to B using less leg power, not from 1 floor level to the next hence the usage of lifts here is moot. If wheelchairs are banned on travellators for whatever reason, they should put a sign at the entrance to inform us. Otherwise boh salah.  Of course it is more considerate and  faster to move along with the conveyer, but there are no rules that forbid the user from simply standing on it and allowing the travellator to carry them from 1 pt to another..

As long as the speed is not too fast for non raised type travelator, then it is fine for wheel chair to use. But need to put up signage to inform and warn travelator users.
