[Tagging] Feature Proposal - RFC - More Consistency in Railway Tagging

[Colin Smale]

What about the difference in signalling systems? As I understand it,
what I would call a Tram is completely under control of the driver.
He/she alone decides when to stop/start, and even which way to go at
junctions. They have "traffic lights" which are interconnected with the
lights for other road users. One tram can approach the rear of another
without any problem, just as other vehicles wait behind each other at
junctions. 

What I would call Light Rail uses a more serious signalling
system, more closely related to its "big brother" where train paths are
pre-planned using some kind of (fixed/moving) block system. 

Is "tram"
vs "light rail" an attribute of the vehicles, the service or the
infrastructure? Can a single route transition from being one to the
other?
