Thanks for the detailed info! The Ericsson system (now ADtranz Ebicab) sounds
like the same one that is used on SLR here in Sydney, although maybe a
different version. The Westinghouse system sounds similar to the Level 2
version of ERTMS (European Rail Traffic Management System). Radio based
signalling is generally seen to be the way of the future for mainline railway
signalling schemes, so it will be interesting to see how able Westinghouse is
to succesfully implement the project.
