Trains via Tamworth HL cant reach 125mph can they?
They can do a
lot more than that if I'm driving!
Although I havn't passed through Tamworth HL in some years now, I
believe the limit through the HL platforms is about 100mph at present for
non-tilting rolling stock. Making the necessary adjustment in the speed limit to allow for tilting trains, the safe passing speed limit for a Pendo (If they had wires up there) would be about 150mph.
Therefore, I'm going to back everyone else up on this and say
Tamworth...Although I suppose the point where the ECML crosses the HS1 link out of St. Pancras could also be a legitimate candidate. 8)
