The problem you're gonna find is that the RCX can only point in 1 direction at
once. Unless you have many spaced around your layout, you're not gonna be able
to control the trains at every point on the layout. That may not be a problem -
if the trains continue running when they lose their IR signal (we don't know
that yet) you may be able to have significant chunks that don't need coverage,
but you're still probably gonna end up needing multiple RCXs - and how do they
communicate with each other if they're using IR to communicate with trains?
