The class 20 is a remarkable survivor. It's one of the earliest of BRs mainline diesel. 20142 is a relative youngster of the class - rolling off the production line in 1966 (with its older siblings dating as far back as 1957.

Top speed is 75mph - about 9" per second in 1:148.

There's a thread on RMWeb dedicated to the class. Lots of nice photos showing the wide range of uses the class was put to.

Beautiful smart loco. Its London Transport liveried 20142. Private owned. My only concern is not giving runs at that speed. Only my thoughts .  Run mine at a slow medium speed ensuring gears settle and motors are not becoming hot


Here is the real loco
.


I took the photo of the real life loco working a treble headed charter



Looks very different and I agree with Webbo.  I primarily run my 20s on coal and steel trains as how i remember but they do haul chemicals and in the real world appeared on Summer Saturday seaside trips and Sunday excursions ir dragging AC electrics when there was engineering work / maintenance on the overhead lines requiring power to be off

Thanks!  Oh, look at that. It's the real thing. Very cool.

That was a very short run just for the video. A proper run-in will take place on my Kato track.

Great photo!! It's simply a gorgeous loco.

A very smart looking loco. It looks like she is capable of a scaled up speed of 150 mph which would be a lot faster than that for your Atlas switcher locomotive.

Yeah, the controller runs hot.    I need to swap it out.

Graham Farish Class 20/0 London.

She's beautiful! She runs very nicely. Great detail.

She's geared much differently than the Atlas She's sharing track with.

She doesn't fit my future setting. Don't care! Wealthy eccentric Old Man Douglas likes buying unique locos for his quaint rural community. 

I'm also tempted by these as they look lovely models. Though trying to justify a maroon set in early 60s Cornwall is a bit of a stretch...

Diverted from the East Coast mainline due to engineering works   

Also found this site with rgb values for Vallejo colours.

It seems that Vallejo 71.130 is a good starting point for improved engine green. RGB values are a bit higher but the balance seems ok.
Add a bit of white maybe?

Apart from the film I  have never heard of it
