This video of Maeklong Railway Market in Bangkok was shot in time-lapse but it's clear that people have to shake a leg when a train comes chugging through.
From Wikipedia:
The railway became famous for its route through the Maeklong Railway Market, nicknamed (Thai: ตลาดร่มหุบ; RTGS: Talat Rom Hup), meaning the "umbrella pulldown market". It is one of the largest fresh seafood markets in Thailand, and is centred on the Maeklong Railway's track. Whenever a train approaches, the awnings and shop fronts are moved back from the rails, to be replaced once the train has passed.
YouTube has a number of ground level videos of the market. Here's one:
