P2 Locomotive Company and related matters

Thought it might be somthing to do with that, thanks.

 

OT, but it's always intrigued me that the Brit's didn't have oval front buffers, but the Duke did - although I think a couple of Brit's gained them in later life?

 

Maybe locos only needed oval buffers if they worked through Rugby ........

 

Here all week Sheff?

 

Just occurred to me that with:
- A shorter boiler.
- Smaller cylinders of a composite construction
- Springs instead of a swing link
= theres a lot of weight gone off the front end of this particular P2...
What would be a creative way of re adjustment I wonder.

 

Can't say that is true. If you look at all of Thompson's Pacifics - particularly the A1/1 which was the longest Pacific the LNER built and was in fact a good foot longer than a P2 as it happens. Not a hard and fast rule.

 

Can't just be the length of the pacific, just look at the Std 4 tank, and their predicestor the fairburn tank both with oval buffers. Is it the distance from the driving wheel to the buffer - in the case of the tank loco the reverse being the worst case with the rear bogie? P.S. Of course the radii of the routes they are intended to run on is also in the mix.

 

Is it possible that we are trying to simplify a complex problem by looking only at a few headline dimensions? It seems to me that the throw of a given locomotive must be related to overhang, fixed wheelbase, design of trucks/boggies and quite probably other factors, and then a need for oval buffers would start with the throw and add to it minimum permitted radius and quite possibly anticipated duties and other factors I'm ignorant of. All to often, and I include myself in this, I fear we enthusiasts start to resemble the youngsters who'd come to the bike shop where I worked and evaluate relative performance of different bikes by the maximum number on the speedo and the number ( 125, 250, 750 or whatever) on the sticker on the side panel!

 

Can'

Can't help feeling that oval buffers are more for 'show' than anything. German locos at least as big as ours - if not bigger - never needed them as far as I am aware.

 

No. 2007 gets its ‘face’ just three years since the project launch!

I'm not a fan of new builds*, but that is already very pretty. And even I will want to play behind the thing and at the lineside when it takes on the Dundee-Aberdeen road!

* I'm not getting into that argument here.

 

I'm not sure it will, wasn't one of the problems that it spread the track on the curves? Whatever routes it does use it will be an impressive sight. When I joined the Trust I said this was the one they should have built in the first place.

Thanks I somehow missed that

 

Isn't track also rather different nowadays?

 

St

Still 4ft 8"1/2 last time I looked

 

Indeed but it's like butter out of the freezer.
(Difficult, if not impossible to spread!)

Sawdust.

 

Not any more - it has shrunk by 0.1mm since the days of steam ...

How many thous is that?! Apologies to @61624 I hope my comment wasn't taken the wrong way.
