Apparently at one time, steam coils were thought to be necessary in services
where we wouldn't even consider them today.
The first pressure cars, Class V, purchased by Phillips Petroleum Co. (PSPX
10001-10003) came from Standard Tank Car in 1927 equipped with steam coils.
I can't imagine butane or propane needing to be heated for unloading in any
place south of the Arctic Circle.
As for the OMI car, although pretty small, a two compartment lube oil car
with coils is not unthinkable.
