I'm new to this sim and I'm trying to run the 1st service under the 43 train I think (sorry I'm at work). I start travel a few hundred and the get a red signal so I stop within a few yards. I then wait and it never gives me the go signal. I tried hitting left on the d-pad and request sorry not sure what it is but nothing happens. I wait like 15min and still nothing happens. One time i did left on the d-pad and it said proceed at restricted speed limit, I waited for 10 or more minutes and it never changed from red. I went forward and failed. Any ideas what i'm doing wrong? Thanks for any help.
