Tornado

quite a good video, its definately doing more than 25mph

 

Err it would be. That was one of the loaded test runs. By the light levels its the last one believed to be at 45mph approx.

 

Here are a few more pics taken in the murk this morning on the second day of public running.

Looked great on Sunday:



For such a beast of a loco it has a rather quiet whistle!

 

Does anyone know if Tornado is working pasenger trains this Saturday??

Thanks!!

 

According to the GCR website 'Tornado' should be working (subject to availability) this coming weekend.

Cheers,

Paul

 

Had a great day out today ! Couldn't quite believe I was looking at an A1 for the first time since 1965; bloody wind made my eyes water! I know the pics have been done to death - but I just have to...........................

 

Had an enjoyable day at the GCR on Sunday very quiet lineside with everyone else at the SVR gala.Fantastic weather especially for the first run at 10.15 with a chill in the air.

I trust that no one who has previously said on here they do not agree with replicas or modified engines are looking at these photos?

 

Nice bit of film of Tornado on "The Railway Channel"

One Question now that Tornado is doing passenger trains on the GC is she now taking steaming fees from the GC and starting to pay her way.

How exactly does this come under 'modified engines'?

 

The geeks answer:

Timing the frequency of the coaches 'clickety-clacks' #-o they were at 1-second intervals.
Given a BR MK1 coach is 57ft, thats 57ft/sec.
1ft/sec = 0.681818182 mph, so 57 x 0.681818182 = 38.86mph.

But the more common length of a MK1 is 63 ft 6 in and not 57 ft !!!

ie. a bit faster ................

 

Its the distance between front a rear axles that counts.
Also is the rail at 60ft joints or 120ft joints??

 

Rightly or wrongly and discussed to death elsewhere, Tornado has many parts made in quite different ways to the original A1s. Some barely consider it to be an A1 as such, but I'm not going any further down that road.

 

Carriage length, not distance between axles, is the determining factor I think.

If you're timing the sound of wheels passing over one rail joint (the nearest or most audible one) then distance between adjoining joints is irrelevant IMHO.

Errm - I think correct me if I'm wrong, but this is possibly a replica or (or should I have said new-build)

 

Hmm... don't think so. The regular click-clack click-clack sound occurs each time the nearest pair of bogies to the traveller crosses a rail joint. The time between each set of four impacts is determined by the distance between rail joints. IIRC, 60 foot rails are most common, but you also get 45ft lengths. Can anyone from the GCR P-Way gang tell us what length their rails are?

Also, you ought to count the number of impacts over a longer period (30 seconds or a minute) to get a reasonably accurate speed estimate. There is quite a big difference between 28 impacts in 30 seconds (56 feet per second, assuming 60ft rails = 34.6 mph) and 32 impacts in 30 seconds (64 fps = 39.6 mph), but you'd measure both as one impact per second. 45 mph is 72.8 fps or about 36 wheel impacts in 30 seconds.

Edit: just realised we are talking at cross-purposes. My formula works for a traveller on board, the previous one works for an observer at the lineside. Ignoring relativistic effects, of course ;-)
