I noticed the cab signal keep the "restrict aspect (red/yellow)" on all the route. This issue is only on the SD70ACe, on the SD40-2 the cab-signal perfectly work (when you pass a green signal, the red and yellow lights go out).
Maybe, I bought this DLC in sale in january, and since january the cab-signal don't run, but before ... i don't now.
Despite it does not work properly well, if you have another train ahead of you, it changes!. What I mean above, is it does not always shown the right light. It is a pity this can not be fixed! Furthermore I used the SD70ACE on Sand Patch Grade, and there - strangely - it works almost perfect! Note: There are several days I did not use any of the 2 mentioned routes. After that there were some updates. So may be, that situation does not happens today, and now it does not works right. I will check on some days.
Yes, because on community presentation videos the cab signal work correctly. It is 2-3 weeks later he got broken with a patch.
