LNER C2/GNR C1 Atlantics - looking for details?

[tbdanny]

Hi all,

I'm in the process of constructing a model of the GNR C1 class/LNER C2 class Atlantics for Trainz Railroad Simulator, and I was after a few details that I can't seem to find. Namely, what were the actual frame lengths for the locomotive and tender, and what was the height of the cab roof and tender sides?

Also, the Wikipedia entry on these beautiful locomotives mentions that the "cylinders were no match for the boiler" and that they were "thrashed" - am I correct in understanding that this means the boiler produced more steam than the cylinders could handle?

Any assistance in this would be appreciated.

Regards,

Bill,

I did do a search of the forum, for the C1 class Atlantic, but wasn't able to find that image. It's exactly what I need - thank you.

Fair point, I suppose...

I built a coal fired Gauge 1 GNR Class C1 a few years ago and still have some of the basic information. I can be contacted through the moderator.

This depends on your point of view.

1. The boiler was too big for the cylinder capacity.

2. The cylinders were too small for the boiler capacity.

Depends on your point of view, really. Whatever, they were very impressive machines.

Hi all,

I've got another question regarding this particular prototype. From what I can see in the photos, the rear axle doesn't appear to be mounted on a separate bogey, but is just within the same frame that holds the driving wheels. My question is did this axle have any sort of sideplay, or did it form a rigid wheelbase with the two driving axles? (I.e. a 4-6-0 in terms of wheelbase articulation).

Thanks for the help,

I assume you've already realised Danny, that the downloadable diagram shows the unique second-rebuilt form of No 3279. Its cab was longer than standard, as well as having the curved roof. I can't remember with certainty at present, but the frames may have been lengthened at the rear to suit the cab. Check the bogie dimensions too.......

Basically there was no side-play on the trailing axle.

Actually the PO was asking about the C2 Klondikes.
