well
mekanism is starting to become abit mainstream tech mod
so was thinking for a Minecart / loader & unloader for Mekanism´s Gasses
thats all
just discovered i needed it for my railway system
and im pretty sure other ppls do too
right now i just use block breaker to break/placer for gas tanks and put them in chest cart
but im sure it will be more Server/FPS friendly to have a offcial Gas minecart

Sounds like an existing solution is available. I don't see any reason to add yet another build dependency to Railcraft.

@mariodk As a in between you could just use a rotary condensator to convert the gas into a fluid that can be transported in in a railcraft cart.

ohh i forgot about that but still would be nice to have gas support so you dont waste power/resources on 2x of rotary condensators
