You are both right. RF absorption is a combination of amount of material and its properties. I think the issue with trains is limited to newer ones with special windows (I think they are conductive - some cars have them too). The combination of shielding from the roof and windows makes it practically impossible to get a fix. I was surprised that I managed to get a fix in a jet aircraft a few months ago - I would have expected this to be a good shield too.

I assumed the reason I had trouble getting reception on board trains because of what their roofs were screened with. I can't believe they'd put much mass up there.
