What is a noun describing the sense of an adjacent train moving off?

Question

Picture this. You are sitting on the station on a train nestling your coffee, sandwich and newspaper.
That train moves off, briefly making one think one's train is moving backwards when it is not. Or - more often still - the other train is arriving so one thinks one's train is leaving already.
I know there is a German word for this, but is there an English word or phrase that succinctly describes this (neither
special nor general) relativistic effect?

LPH · Accepted Answer

"Visually induced illusory motion" is the generic term; the particular sort associated with trains is "vection" (gizmodo).

Decapitated Soul · Answer

I think that's called vection.

Vection: vection is the sensation of movement of the body in space produced purely by visual stimulation. [Encyclopedia]
