Were the BR standards fitted with a whistle to a Derby LDO drawing of 1875? I thought the BR Standards used a GWR whistle along with the injector and SR Clack valve Edited July 6, 2021 by John Besley . 1 1 Link to post Share on other sites More sharing options...

Agreed, it looks more like a 'rigid tender' rather than what we'd think of as a tank loco. There aren't even any tanks alongside the boiler. 1 Link to post Share on other sites More sharing options...

Until the closing credits I thought it must have been 16mm. In quality it certainly beats so much UK film from the same era.

It's been digitally scanned frame by frame and then stabilised, probably also colour and contrast adjustments. It really brings the past to life seeing it in near contemporary quality. Here's a little video outlining the process - check out the home-made scanner! Looks like the early days of the space race! and here's the results compared to the original...

Presumably it doesn't suffer from most of the issues that tender first running creates, and therefore doesn't need turning.

The Forney 0-4-4 was used for similar duties, I believe they ran bunker-first where possible American railroads didn't have the problem of accommodating stations amid medieval street plans, and even their suburban stations are large by our standards Edited July 8, 2021 by rockershovel 3 Link to post Share on other sites More sharing options...

I think the arrangements for the motion was derived from Hughes' Pacific, but the cylinder arrangement was de Glehn via Churchward with later modifications on the Duchess.

Convention, counting from the smokebox end, seems to differ. The Glyn Valley locos were classed as 0-4-2 despite being intended for cab-first operation. The later SP cab-first locos were 4-8-8-2 counting from the cab end, being very much designed to be operated in one direction only.

Looks like it's a DB class 50 or 52 2-10-0, in which case it has 2 outside cylinders, with cranks presumably at 90°. An A4 or Jubilee has 3 cylinders, so will have that distinctive "3 beats to the bar" of a 3 cylinder engine. 1 Link to post Share on other sites More sharing options...
