Solid axles are almost universal on all trains. I don't know of an
exception, although I expect someone will soon post one.

BART is a rapid transit system and they should not have been using 19th century technology.

Do you know what technology other cities' transit trains use?

As a mechanical engineer you're telling me you can't answer that? All of the rapid transit systems in the world have cars built in I think three assembly lines. They are all identical.

I notice you didn't answer the question.

You are growing curiouser and curiouser.

New York Subway system and all the rest are generally built by a German firm - Bombadier I think.

Why is it you do not know anything yourself and expect others to feed you information you could discover for yourself if you entire idea was to learn rather than bitch like a little whinny dog?

Bombardier is Canadian not German.

Doug - I know that but the Rapid Transit car division is in Germany if memory is correct. In any case - BART has gone through 4 upgrades now and they ALL have the same problems as steam engines - solid axles.

Because trains run so seldom it requires half a century for the rails to wear enough to require replacing. Rapid transit systems have trains running mere minutes apart.

I tried to convince they when I worked for BART but they know what they're doing. Derailing vehicles.
