Here you go:
Bolton - Hellifield attached.
Never seen one Worcester - Stourbridge - Birmingham (if you find one, post it here!) but Crewe - Carlisle is easy enough to obtain. It's in the Ian Allan book 'BR Main Line Gradient Profiles'. Out of print but plenty available. There's a few on Amazon and eBay right now.
Thanks very much for that. I've ordered a copy of the book you mention - I had one years ago but it's long since disappeared.

GazK, you are in Wiltshire I see, if you like you can borrow my BR Gradient Profiles book from Ian Allan, I have a hard copy. I have no scanner but you can borrow it for free![]()
