Alex Hynes of ScotRail Alliance said there would be significant improvement next week
The boss of the ScotRail Alliance has promised improvements to services after a surge in cancellations.
Alex Hynes said problems in training staff to operate new trains were the main reason for recent delays.
Hundreds of services have been cancelled or had fewer coaches, leading to overcrowding, since the introduction of a new timetable.
Mr Hynes apologised but said travellers should notice "significant" improvements next week.
