One thing I intend to do, regardless of the model being produced, is a benchmark test, namely comparing reliability against an RTR equivalent.
seeing as the chassis will essentially be a solid piece similar to that of an RTR model, it will be expected to hold up to the same wear and tear as a mass produced model, have the same reliability, take the same curves, etc. obviously as it's a kit I won't be engineering it to be as tough as a railroad model, but you get the idea.
in order to set a benchmark for reliability I intend to at some point purchase a locomotive by one of the major manufacturers and test it from new till it fails, which basically involves setting it on a rolling road and leave it running at a steady speed, probably half-speed on the dial, and leaving it for a few weeks or even months, once that fails I'll calculate the total hours then set a chassis from an upcoming kit and leave it running till it also fails. if it reaches anywhere near the number of hours it'll count as a pass.
I'll also be experimenting to see if cold cast brass is any better or worse than standard resin.
consequently this will mean that it will take a while longer for any new model to finish development, as any alterations have to be made and subsequently tested, which could take months. however, I want to ensure that, in terms of the running characteristics, it's a good as possible with the manufacturing techniques available.

that's something I've been meaning to ask. I originally thought it was located at shildon, and my aim was to visit there to study it for any details that arent on any scale drawings. but then I read that it was at NELPG's shed located in the same building as the P2SLC undergoing boiler work.
any concrete confirmations of it's location and completeness would be greatly apreciated
