A very interesting comment in there about the reduction in services on the City Widened Lines in January 1915. When time permits I'll have a look at my Widened Lines TT from July 1915 and compare it with the Bradshaws. 
The CWL is 'just off my radar' in terms of interest, but having spent part of my evening sorting out the CWL part of the sub-surface TTs I'm minded to do a bit of digging.
 fear not - I don't have a collection of Bradshaws - but to paraphrase the old AA advert: I know a man who does.
If we can have A 244/R 246A, ODX 246A/R 246B, A 246B/ROD 1, OD 1/ROD 2 then I'm going to have A (7)88/R (7)90A, NHX (7)90A/R (7)90B, A (7)90B/RNH 1, NH 1/RNH 2 and hang the consequences!
