Just to say that in the June RCTS Railway Observer "Nostalgia Corner" there is another feature on 40 years ago.
It concerns the opening of the new spur from the SMJ at Stratford to the GWR with consequent rationalising of signalboxes (due to take palce on June 13).
This new connection was seen as bad news for the Stratford to Broom section of the SMJ.
The article mentions various trains used for learning the new route from Woodford to Honeybourne and mentions Woodford L1 tanks 67740/71 (I remember the latter on the Banbury shuttle). Also 43106 (another Woodford engine - I hadn't realised that these were shedded there) and 48402 (a Tysley engine) running between Banbury and Stratford (presumably using the connection at Fenny Compton?).
Interestingly, and surprisingly, between midnight and 5am on an April Sunday thirty freight trains ran between Broom and Stratford and vice versa.
