It was the diesel from Victoria (Manchester) to Carnforth, there we were hooked up with the Steam engine (the one used in Harry Potter and carrying the side plates from the film). Then we set off for York. Got stopped short of Leeds, due to the high temperatures, and risks of fires from a steam engine. Rolled into Leeds, where the diesel then had to pull us backwards into York as Steam was banned. We were an hour late, so did a very fast Train Museum visit, then went to get food. Jumped back on train, but it was the diesel all the way back. Steam had now been prohibited in the area. Must say the old diesel was a quick and smooth beastie.
It was a tough journey as it was so hot - literally cooked in the carriages. If we do it again, we will pick a shorter day out, not 14 hours !!
