Am having problem with this scenario 55-CN.
After coupled to the delivered cars in "Siding 1" (in fact, "Service 4" left 4 cars, not only 3 as instructions suggests), the (blue) path doesn't change to straight-wye section, so I can't reach X-22 trackmark in order to pull back into the Yard 4. Scenario always invariably ends when "Service 1", despite of any red signal, go ahead till collide to "My Service".
Thanks,
Machinist.
