If you head to the petrol garage at Morrisons you should see front of the train I saw it from the bus today home
Thanks for the info, I'll go have a look. There was a good vantage spot from Crown (the one where the road loops round) but I tried to see the 37 from there but the trees now block the view. Then again the spot just above the Eastgate centre might be good.
Edit - I've been down this morning and it's sitting over the back where the 47 was over the winter, it was hard to see past the cars beside Morrisons but you can just see it from Crown:
I've tried seeing engines here from the fence on the other side but it's all quite overgrown there.
Why did they leave the engine rather than haul it with them since I assume it's unlikely to leave under its own power? 37403 was also left here last year when it had trouble on its railtour while the sleeper 67 hauled the carriages back down.
