In the late 1960s I photographed MHAX 1154, a helium car built by AC&F in
December of 1960, including a number of close-up views. Nominal capacity
was 100 tons and light weight was 240400. The weight was mostly in the
very heavy steel tanks which were designed to hold helium at very high
pressures - and, yes, helium under pressure is NOT lighter than air. This
car had roller bearing trucks and, like all the helium cars I've ever seen,
it was equipped with clasp brakes.
