75MPH? Sensible for all parties concerned IMHO, makes the journey behind the traction longer too!

Well I saw what I belive to be a WCR Class 37 pass through Warrington BAnk Quay last week and it was doing I would say in excess of 75mph.

I would Imagine that Hertiage Locos maximum speed allowed can depend upon wether or not it is carrying passengers or not.

There is also the paths to consider on which route it is taking as rember Tornado on Top Gear was only allowed to do 75mph for pathing reasons Iam led to belive.

I know tornado is steam loco but I was using it as an example...

I think you will find that All steam locomotives allowed to run on NR (at present) are restricted to a maximum speed of 75 mph.
Certainly not due to "pathing".

If it was light engine then it is a max of 75mph IF the line speed is 90mph or above, anything else is 60 or below.

At Warrington, the driver can be doing 75mph if heading south, or should be starting tp brake down to 60mph. It is very hard to judge speed from off a platform as most speeds seem fast as the train goes past.

[QUOTE=scotrail;43240]It was hauling a Set of Cariages Empty I assume..

A class 31 at 100mph, is what nightmares are made of.
The ride at that speed would be like all the roll coasters in one go, some thing to avoid at all costs.
At 45mph these engines bounced about , so much so that it would make your tea splash out of the cup when it was just damp.
The only other bad riders was a Shark Ballast Brakevan coming down to Huddersfield from Standage Tunnel at 35mph.
It was so rough you had to wedge yourself into the seat and think of england.

I think you will find that the class 31's were limited to a maximum speed of 90mph and the very early numbered ones to 80mph.Although I agree that they were very "bouncy" machines at speeds above about 50mph.At Saltley we used to work class 1 trains with them on a regular basis,usually Birmingham to Norwich and Norwich to Birmingham trains.

Good news on the Class 47 front from Mangapps - its working again!!!
There was a poor contact end which meant the relays werent making when they should have. Hence plenty of TLC required to make sure they stay clean!! Its amazing how much dusty crud mixed with moisture can work its way into the smallest of places where you just cant see it properly. But how do you keep that sort of environment spotlessly clean as it must have been when manufactured. Still it is 50 years old so we all need cleaning behind the ears at some stage. It was great to feel it accelerating way if only for a moment on the short stretches where that is possible. Now the blue paint comes out so that a new coat can be applied ready for the summer season. Marvellous!!!
