Why are new trains so much heavier? All they have over the old ones is

Why would you imagine that: consider that the typical weight of a family
car has close on doubled over the last 35 years - almost all due to crash
protection (with some down to NVH supression and some to a/c and
such). The weight growth of trains looks very modest by comparison.

NVH?
