On the London Underground, on the Central line, why does the train sometimes jolt as if it's lost power for a second as it's leaving the station?

Sometimes it happens just once, sometimes it happens two or three times. It doesn't seem to happen consistently at particular stations, and it feels like it's more likely to happen when the train is crowded (although that might just be my own confirmation bias). My hunch is that it's a safety feature of some kind, but if so I can't figure out what might be triggering it. Anybody in the know?
