After making a Journey Planner API request from Aldgate (940GZZLUALD) to Greenford LU (940GZZLUGFD), one of the result’s walking legs listed level stairs as an obstacle.
The legs listed were:
- Coach 735 from Aldgate to Cannon Street
- Walk to Bank (with down incline stairs, level incline stairs, and down incline escalator as obstacles)
- Central line from Bank to Greenford
I’m really confused about the possibility of stairs being level rather than going either up or down??
