Hi all,
I have been asked to give a "Signalling for Dummies" presentation at an NR Infrastructure Projects Directors' away day. Does anyone have a Powerpoint presentation I could borrow with some graphics that provides a high level explanation of signalling, e.g. starting with bobbies with flags, absolute block, TCB, 2-4 aspect etc?
many thanks
