And how long did it take to get it right Ian?

The ATP system employed by QR is what I'd consider only suitable for
where it is employed. Inter City freight, not an urban rail system.

Why?

I'm not knocking the Westect, it's for what it does, but an urban
system requires a few more units than your standard passing loop.

Look at a trainstop, or an AWS. Look at the TPWS. What features set
these systems aside from the AEI track transponders we deployed?

seeya!
