PlayStation Trouble With Tank Trouble

on Tees Valley Line in the scenario Tank Trouble after uncoupling the pca with hot Axle you couple to the formation and run around after this you are stuck at a red as is a class 20 at another red and you cant proceed

 

I don't have br class 20 bought, but in that location i have br class 37s

 

In the scenario "Tank Trouble" you have to be fast, try to keep these timings and TY553 will be white.
