People not cleared from out of service train, train goes to sidings

[ColmmacO]

Maynooth train pulls into pearse a few minutes late. Passenger info displays show next train as greystones. Two passengers (most likely tourists) get on last carriage. No staff member walks the length of train to clear carriages. I think the guy on the platform walked about 3 carriages before he gave the all clear to the driver. Doors close. People on platform try to make eye contact with the two on train to no avail. Ticket inspector seems to notice. Train pulls off towards sidings. As train is half way down platform staff member notices but its too late.
I wouldnt be suprised if the two on the train got a good dressing down from the driver despite it not being their fault.
Perhaps, I should have been a bit more self confident and waved a bit more frantically to get their attention, but I think this is fairly bad form from the staff on duty.
