A discussion on whether to investigate introducing greener trains for Aberdeen will be held next week.
Aberdeen councillor John Reynolds had earlier tabled a motion calling on Transport Scotland and ScotRail to replace diesel rolling stock with trains powered by hydrogen.
But councillors decided to refer the motion to the council’s city growth and resources committee which meets on Tuesday.

Mr Reynolds has requested that city council chief executive Angela Scott write to leaders of other local authorities urging them to back hydrogen trains.
He has previously said the trains would eventually pay for themselves as hydrogen can be generated from wind turbines.
The Independent councillor also said hydrogen trains would lead to cheaper fares for passengers and free up cash for line maintenance – while emitting less pollution.
