Hi. I'm a member of a tourist railway with coal fired locos, but I've never seen an oil fired steam loco up close (except an incomplete one in a restoration line) and was wondering exactly what they burn.
Do some use the bunker oil they were designed for? Is it less expensive than diesel fuel? I've heard of some that burn waste oil, but don't know whether the firing arrangement differs between fuels.

Welcome to the forums. I can't speak for all operating oil burners - but the ones I am familiar with burn used engine oil. That includes Union Pacific's 844 and 3985. Unless special arrangements (ie. long-term contracts) have been made getting heavier oils on a retail basis has become more difficult

Thanks for the replies, they answer my question nicely!
In the late steam era in Western Canada, CN had a lot of oil burning steamers and the earlier posts are correct about the use of bunker oil.
CP has a restored Hudson, #2816 that was converted to burn fuel oil the same as its diesels simply for the convenience. It smells like a diesel too which is a little wierd.

I can confirm to some extent what another individual posted in this thread. Here in the Black Hills of South Dakota we have the Black Hills Central Railroad, otherwise known as the "1880 Train", and the last time I had ridden it in the fall of 1998, they told us that they burn recycled motor oil in all three of their steam locomotives. And it would not surprise me that the UP would burn the same in 844 and the 3985.

SVRR No. 19 burns waste oil now, but when I was learning to fire, we took donations of whatever someone wanted to give us. One day my trainer was explaining what a "white flame" was, and looked into the firebox. She was surprised to see a green tinge to the fire, and told me so. Later, we surmised that there was antifreeze in the mix. Shortly after, SVRR started restricting donations of mixed waste, and buys filtered waste oil.
Another thing we would sometimes get was bunker C, which is much thicker. Getting it started is not easy, until there is enough heat to put steam into the tank heater. Once, I was conductor, and the engineer kept stopping the train to ask me how to get the fire to burn hotter, because he and the fireman had done everything they could think of, including turning off the tank heater, to conserve what steam they could generate. It took half the day to convince them that we had a larger-than-usual amount of bunker C, which required much more heat to get flowing to the atomizer, so they needed to run the tank heater until the temperature reached at least 140 degrees, and 180 would be better, before they shut it down some.

Although a useful metal, it is very toxic to humans. Am I misinformed or is the amount insigificant in the in the steamer exhaust?
