Better quality tinting films have metal particles, which may affect signal
propagation... Not a big deal though...

What sort of speeds so these vehicles in which you are interested travel? I
think that pass-overs from cell to cell would be the major problem. Cells on
highways for example are specially designed, located, and "aimed", and are
quite a different kettle of fish to suburban cells. The cells you are
connecting to would be there for the stable population, rather than the rail
transit system, and this I presume is where the problem lies.

Of course the construction of, and electrical and electronics systems
within, your Rail Vehicles would also play a major part. What sort of window
to Metal ratio are we talking about?

(P.S. I've never been on a train :)

Having a look won't tell you much about the tinting film
