Can anyone tell me how to set up and wots needed for british high speed junction signals? (ie flashing yellows) I saw something about this I think when i was using trainz 2006 but didnt require it at the time so didnt read about it, im now using trainz 2012 and as usual cant find anything on the subject when u want it! 
Obviously I know how the signals work in real life but are there any in trainz? id be grateful if someone could point me in the right direction
