It's Easter weekend and an influx of rival football fans at Glasgow Central puts extra pressure on the staff and transport police as they segregate the fans heading to Hampden. There is a new team member on the concourse as police dog recruit Marvin is put through his paces during training.
Outside Central, the Network Rail ecologists work to help a peregrine falcon nesting on one of their bridges. And the engineering team get to work on the Argyll line track repairs.
