Are TVS diodes necessary if you're still running all postwar, and nothing "modern"?

Nope. Some modern components are sensitive little buggers. Especially memory oriented chips.

Post war is more robust electro-mechanical for the most part.

That said, after GRJ pointed it out once, TMCC seems pretty robust to me too, but for a few pennies a TVS is additional insurance worth while for command folk imo. I only have two TMCC. I don't use sound, and don't care if the boards die, so have abused them without a hitch.

   MTH's approach early on didn't impress me at all in that way. I think my brother would have saved a whole lot of cash using TVS. A few never made a full loop, dying on the switches.
