Help on tutorial 4!!

[Trailltrader]

I guess I'm retarded- but I can't get past tutorial 4 on Trainz Simulator 2012! If I go past the red stoplights the tutorial stops. If I go backwards to the loop 1 it says its been turned off by the computer. So what am I supposed to do? I've made this trip like 4 times- what should I do now? Thank You

Go up to the red signal and stop. Then change the direction on turnout 'loop 2', just ahead of your train. This will change the red signal to green. Proceed. (Meaning no insult, I'm not quite sure why you need to be told this, as it is all spelled out in the tutorial pop-up messages. Are they not coming up for you?)
