E.W.R. Line Speed?

[Chrius56000]

. . .According to the March 2025 Edition of the L.N.W.(S) Sectional Appendix, the E.W.R. has a differential speed restriction of 75/100 mph HST over most of its length and the "Signalling" column quotes "TCB" with Axle Counters over the whole length, supervised from the Claydon Workstation of Rugby ROC and Marylebone (Oxford) over it's western section to Bicester, with signals plated "OB" (Oxford–Bletchley).

. . .Will the class 196s be restricted to 75 mph or will they be authorised to take advantage of the "100 mph HST" when the passenger services begin?

PS!

. . .Just for comparison, has anybody got a copy of the Sectional Appendix that was in force when the route was only open to Claydon Junction from Bicester and mothballed to Bletchley, as described in the "Disused Stations" website?

The December 1987 Western Region Sectional Appendix for the Marylebone/Aylesbury/Banbury Area says that Summit of Bletchley Flyover to 18 MP was 30 mph in both directions and 18 MP to Bicester Town was 40 mph. There were several restrictions down to 25 or 15 mph.

1997 Midlands says similar. 15mph through Claydon, 25mph over the flyover.
