Panelling

[150001]

This is a slightly different Traction stock question. How are the interior panels fitted together and stuck down onto the "walls of the train?" Do they slot together and what is used behind the panels to keep them in place. Is it bolts, nails or strong adhesive? How are the panels replaced too?
Finally are the wires easily accessible (free hung) or in some sort of boxes. I'm mainly referring to newer Bombardier, CAF or Siemens. Sorry for the countless questions and thanks in advance!

P.S How could any vibration and rattling be reduced; I always though much more soft material behind the panels, with magnet locks and much stronger material.

I've always thought behind the panelling is a metal framework with holes drilled at regular intervals in the metal 'bars' that form the framework so the interior panels can be bolted on? That was a total guess so please correct if wrong!

one way to stop rattles are either make sure any parts are exactly the right shape and size down to half a millimetre. Or another alternative would be for example any hinged parts like the ceiling panels on a Turbo or Electrostar, line the edges with a soft substance, of course in a hidden manner so not to spoil the aesthetics.

Your suggestion for what is behind seems sensible, whether it is or not we'll hopefully soon find out! You're right that really it is just more care needed; I've always thought that a soft material (similar to the stuff for soft toys) behind a rubber sealant would be beneficial.
