Is the 'great extension lead' needed to remove the 75mph limit for electric traction?
I'm guessing it must be, because the line will be full of electric traction.
NR said last week: “The current timetable assumes train speeds of 75mph. We are currently working through all the technical analysis in preparation for a speed increase to 100mph in May.”
TPE have said Anglo-Scottish services will resume from Bolton, but waiting for confirmation of the line speed change.
As RTT stands at the moment, TPE trains don't stop at Bolton and the new 319 diagrams are mainly timed for the old units (from what I have looked up).
The TPE timings seems to reflect their rolling stock capabilities though.
Looking at the new 319 diagrams, makes me think if they have enough units, hence DMU timings as back up.
