Yes the later lever frame at Hitchin Yard was located in the rear of the box the same as the lever frame was in Welwyn Garden City.Dave Cockle wrote: ↑Wed Dec 27, 2017 1:40 pmIn response to your query re the locking frame at Hitchin Yard:-
The original frame was Stevens and Co and located at the the front of the box. This is the one in the photo you attached.
A new LNER RS Co frame was installed in the rear of the box in 1946.
Personally I usually prefer boxes with there lever frames located in the rear of the box rather than at the front.
