I visited Waverley Station yesterday to see the mock-up of the interior of the new Hitachi electric trains for the Edinburgh-Glasgow Queen St route. Worth stopping by to try out the new contoured seats, luxuriate in the leg room for tall people, and to pore over the schematics.
Three-carriage and four-carriage sets are planned, but each will still only provide for two bicycles. The bike space will be 2.34 metres long, multi-functional with tip-up seats, and there's a separate area for people in wheelchairs.
The space between back-to-back seats looked enticingly Brompton-sized but I didn't get a chance to experiment.
