Hi all, I did train despatch at BHM New St for 12 years finishing in 2001. I never came up against the TDCT. I was tested on dispatch as part of my 6 monthly Rules and Regs check to make sure I carried out all the train dispatch stages in correct order and on time while having to assist any passengers who happened to come by. It did certainly call for concentration! Never heard it referred to as TDCT, although times and safety awareness have changed drastically. Anyway, good luck Winks, sure you'll hack it!
