If you didn't have that IV HUD up, I'd call that Fake News and say it's IR. Cause I never thought I'd see a working IV train. But a promise is a promise, so off to make steam engines I go!

Well, once I get a vehicle that has crates for coal in it... then I can poke that physics with a stick. Cause somewhere, burnable things need to be stored.

Here's a locomotive with crates for coal in it... :sans:

Provided picture of Locomotive and tender, though this will require vehicle to vehicle transfer of items

The E2 Class which what Thomas the Tank engine and I presume this Locomotive was based after actually has a small coal bunker on the vehicle itself that is at the back of the locomotive. Coal could be taken out of crates placed there

Hey now, no double-dipping! That's IVV content, not WARK!

Yeah I know it's IVV. I got the image from boot2big's Curseforge page for IVV. What's with WARK?

Now now, you know what that is. It's on your pack's Curse page even!

Guess I'm kinda confused still, yes WARK has some agriculture stuff in IV Farming, but that's not in RandallAg. But I don't understand what this had to do with WARK to begin with?

I posted the image because I'd thought It'd help the ticket move along, and gave an explanation on the E2 having a coal bunker at the end of it since you asked for a vehicle model
