Sometimes, you see a pair of class 37s working top tail with two barrier vehicles and a unit in the middle. on one end there is a hook coupler and on the other is a either a dellner, what couples up to the 801s and 395s, tightlock (465s, 150s), and whatever the London Underground uses so we can couple up to Bakerloo line trains. This could be painted in Rail Operations Group dark blue. I have painted them myself but I can’t drag a unit in the middle Please Look into this thank you. All it needs is a coupler added on to the end. Thank You
