Does anyone know why the Class 91 is sometimes run blunt end first?
Yep, they run it blunt end first when the pointy end is facing towards attached coaches and the blunt end isn't.
Sometimes there's a 67 thunderbird parked at kings cross maybe for this sort of thingMust be a right pain to sort out once it gets to kings cross. I guess another loco needs to drag the while lot to Bounds Great for the loco to run round.
There was a service recently which involved in blunt-end first:

Is that due to aerodynamics or the fact that they weren't intended to go 125 or 140 blunt end first?They are limited to 110mph when running blunt-end first as well.
Q?. Wasn't there a programme to refit the 91's with a 2nd pantograph?Aerodynamics on the pantograph knuckle putting too much load onto the OHL.
I think it was 91114 had that mod done as a trial fit. It was decided it wasn't worthwhile, so I think it has reverted to a standard pantograph, though it retains the cab roof modifications.Q?. Wasn't there a programme to refit the 91's with a 2nd pantograph?
ISTR that there are photographs of such a device (really 2 pantos on one frame) in a magazine

The DVT only has one driving cab, isn't powered* and is supposed to remain coupled to the rest of the set, so there'd be no point in putting it blunt end first!Whilst its not that rare to see a 91 with the pointy end coupled to the coaches, don't remember ever seeing a DVT the same.

The Mark 4s have Tightlock couplers within the set, so the only vehicles that can be coupled to normally are the outer ends of the DVT (pointy end) and the TSOE (end with no gangway).Whilst its not that rare to see a 91 with the pointy end coupled to the coaches, don't remember ever seeing a DVT the same.
