Scratch

I recently made a railroad base.  I uploaded a project with it ( http://www.scratch.mit.edu/projects/trolley8/2184107 ) and soon discovered that the green sensor on the locomotive doesn't work.  I tried to fix it and failed.  The trolley turns, but doesn't stop and wait to be correctly alaiged before moving foreword, thus making it go off the track.  I'm working on other games with the base and the same thing happens, not just with the locomotive, but with the cars and couplers, too.  I've tried putting the seperate sensors in seperate groups, completely re-creating the script, rearranging the order of the blocks, and MANY other failed attempts to fix it.  Is this a glitch in Scratch? Could somebody help me fix it? I would greatly appreciate some anweres to those questions.

Thanks,
Trolley8

The script looks like this:

[blocks] <when I receive[ start]> <forever> <repeat until> << << < <not> color[ green ]is over[ black ]> >> <or><<  <not> <color[ yellow ]is over[ black ]>   >> >><if><color[ green ]is over[ black ]> <turn cw( 1 )degrees> [/blocks] etc. [blocks] <move( <{ speed }> )steps> <end> [/blocks]
