Hi matey, these are known as Tractors or Growlers, similar design to the deltic to the untrained eye. The deltic's nose is alot larger and its a hell of a lot more powerful too :)

Great catch, be good to see them back in service.

I saw these two locosgoing up the M1on tues or wed, look huge on the trucks.

Intresting video! glad to see a 37 being saved! Was the trailer and lorry remote control? Ie the guy at the front with a cable to what looks like a controller?

Interesting to watch!

Interesting to see too :)

Was this loco built at Derby?

Haw dare they spray paint on the 37
