After reviewing all the pertinent discussion about the new Fox Valley B&O wagontop box car it appears that at least the first two paint schemes are legit and were in use before 1950. Sincere thanks

How would this be done, particularly after a load like tar or ashphalt? How would you scrub the sides of the tank? Or don't you think this is necessary? What about getting the last little bit of

I added a couple of photos of drawings for NKP single deck stocks cars. In my album for NKP single deck stock cars in the photo section.

I work in a full service tank car repair shop and I can tell you that most customers use the bottom outlet far more than not for off loading all products. I'm not sure if this was the case in the

I have a photo from the 1920's showing an Imperial Oil tank car being unloaded thorugh the bottom valve. But using these valves can sometime be attended with problems. I was told (at a "TransCaer

Thanks for posting the photos Doug. Back to my original question. I want to know about the trailer with the boiler and engine driven pump! Thanks <G> Clark propst

Here is a link to a 1950s Santa Fe employee training film titled "Payday". This twenty minute short starts a little slow but then goes on to show a lot of flat switching action featuring nice slow

Fascinating photos--thanks Doug. Some tanks had a "steam jacketed outlet" (ACF's name, illustration in 1925 CBC) that heated the valve and outlet pipe area. It looks to me like the small trailer had a

Group I have posted the two photos that started this thread, per Clark's question. They can be found (when approved) in the photo album MSTL. The photos were taken by Vern Wigfield in June of 1954 in

Hi Tony, it seems you misinterpreted by response to Jim Sabol's query. I'm aware that the valve is inside the tank, with the handwheel in the dome. The tank can only drain by gravity if the commodity

The bottom outlet valves used on steam era tank cars were 4 & 6 inch plug valves, the same design that's still in used today. On the tanks with expansion domes the valve handle (wheel) was located in
