Re: Need Help with GATX Tank Cars from the 1950s

Could be an insulated ICC 103. I think many insulated tank cars
were 103's, not 104's. The ICC specifications require that 104's
be insulated, but it does not say 103's must be non-insulated.
In fact, the ICC spec says that a 104 is a 103 with 2" of insulation
and a minimum 2% expansion dome.

A 105 is a high pressure car and has no expansion dome.

Definitely an ICC 104.
