Push aside (5)
I believe the answer is:
shunt
'push aside' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for shunt that I've seen before include "Transfer a train to another track" , "Arrange wagons; minor accident" , "Type of road accident" , "Divert into alternative course, like train" , "Move wagons around" .)
