Platform
Both
None of these
Answer is Right!
Answer is Wrong!
The correct answer is C. Both.
The guard shall exchange alright hand signal from both the path and the platform while the train is started from the station. This is to ensure that the train is safe to depart and that there are no obstructions in the way.
The guard will first exchange an alright hand signal with the signalman on the path. This will confirm that the path is clear and that the train is safe to proceed. The guard will then exchange an alright hand signal with the platform staff. This will confirm that the platform is clear and that the train is safe to depart.
Once the guard has exchanged alright hand signals with both the path and the platform staff, the train will be allowed to depart.
