I realised that the track plan that I posted at the start of this blog was not very clear so here is a better version taken from Track Layouts Sec 32 East Shropshire by R A Cooke. This is an excellent series of track layouts and recommended. The part I am covering is the section top left of the diagram but it also shows why there was a loco shed at the junction.

Originally the line diverging from the main line not only served a number of Iron Works near the junction but continued for a distance to service Wombridge Iron Works and it was known as the Wombridge Branch. Later after the building of the Coalport branch, Wombridge Iron works was servied buy a connection from the Coalport branch.

Another view of the loco shed and Pannier tank.

For those who are interested in the railways of East Shropshire I have written a book which may be of interest it also covers the Lilleshall system as well as Granville Colliery as well as Wellington, Oakengates, Coalport, Coalbrookedale, Buildwas Power station. Available from Crowwod Press.
