I was recently trying the esc vrt on tsw2 and found the br 66 was a option to pull it but while trying it on tsw2020(without useing OTR or SP options)there was not option to use the br66 as lead so was it ever a option?I had never had esc for tsw2020 until recently.
Did you use the right br Class 66? You can also use one from GWE via layers, but only ECW (This is code for East coastway, not "esc") one. GWE one comes in DB schenker and EWS, but you can distinguish it from ECW's. Just render one and the second EWS livery. The right one is that which render is nearer
