Hi, Just having a conversation which has turned into why GPS, DAB radios and
other stuff doesn't work at all well on the more modern rolling stock i.e.
not picking up a signal. I'm guessing it's got something to do with the
window materials, but just wondered if anyone knew here?

Well GPS probably doesn't work because the trains moving all the time
and all the clutter between you and the low down weak satellite signal
is killing the reception. As for DAB , dunno, perhaps the windows are
designed to block mobiles and block DAB too? Does FM radio work?
