It was the height of the postwar era and Lionel trains were all the rage. Children across the country begged their parents for a Lionel train set, eager to experience the thrill of watching their own train chug along the tracks.

But there was a debate among train enthusiasts about which type of train was superior: those that used smoke pellets or those that used smoke fluid.

On one side of the debate were the traditionalists, who swore by the classic Lionel trains that used smoke pellets. These trains relied on small pellets of smoke-producing material that were inserted into the train's smokestack. As the train chugged along the tracks, the smoke pellets would heat up and produce a puff of smoke, creating a realistic effect.

On the other side were the proponents of the newer trains that used smoke fluid. These trains had a small reservoir of smoke fluid that would be heated up and produce a constant stream of smoke, creating a more realistic effect.

The debate raged on, with each side fiercely defending their preferred type of train. But one day, a young boy named Tommy stumbled upon an old postwar Lionel train set that used smoke pellets. He had grown up with the newer smoke fluid trains, but there was something about the old-fashioned charm of the smoke pellet train that appealed to him.

Tommy eagerly set up the train set in his room and inserted the smoke pellets into the smokestack. As the train chugged along the tracks, producing a steady stream of smoke, he realized that there was something special about this type of train. The smell of the smoke pellets, the faint hiss of the smoke, and the way the smoke seemed to dissipate in the air all combined to create a truly unique experience.

Tommy became a convert to the smoke pellet train, and he began to collect more and more postwar Lionel train sets that used this type of smoke. He loved the nostalgic feel of these trains and the sense of history that came with them. As he continued to collect, he became more and more convinced that the smoke pellet trains were superior to the newer smoke fluid trains.

Years went by, and Tommy's collection grew. He had amassed an impressive array of postwar Lionel trains that all used smoke pellets. And as he sat in his train room, surrounded by the sweet smell of the pellets and the steady stream of smoke, he knew that he had made the right choice.

For Tommy, it wasn't about which type of train was superior. It was about the connection to the past that came with the smoke pellet trains. They were a part of his childhood memories and a piece of history that deserved to be preserved. And as he watched his trains chug along the tracks, producing their steady stream of smoke, he knew that he was keeping that history alive for future generations to enjoy.

I've scraped out enough of 50+ yr old petrified smoke pellet goo out of burned out PW smoke units to be a liquid convert. If a PW smoker still works in any form, it stays intact but if the heater's burned out and the bowl is full of old pellet yuck, it gets converted to liquid. Anyway, now I can run scrapple scent.

@ADCX Rob,

With 'pretty much' the same formulation as the 50s/60s?  I read online (and of course that could be a problem) was that the reason they apparently stopped being made was that there were chemical compounds in the tablet that could be used for 'other' purposes.

The chemical that the smoke pellets are made of is listed in the MSDS as Skin irritation:  can cause skin irritation, including redness, itching, and rash.

What I read was much worse than that, either used for making illegal drugs, or could be used to create explosives.  I don't recall exactly which one, but the feds shut it down allegedly.  It was over a year ago when I looked into it.  I'm pretty sure it wasn't a bogus website or just some urban legend, but it's the internet.  Who knows?

The original formula for Lionel smoke pellets from 1946-47, which had Lionel catalog #196, was problematic. The active ingredient was ammonium nitrate. Among its many problems are its toxicity, corrosiveness, and explosiveness. Lionel didn’t initially realize how problematic the substance was, but they learned quickly when a ship full of it exploded outside Galveston Bay off the coast of Texas in 1947, the deadliest industrial disaster in United States history.

If ammonium nitrate sounds familiar, it was also the active ingredient in Timothy McVeigh’s bomb that destroyed the Alfred T. Murrah Building in Oklahoma City in 1995.

Lionel did not use this chemical on version 2 of the smoke pellets that they made until 1973

A couple of reasons Lionel quickly dumped the 196 pellets is they were (are) very corrosive. Seen how many smoke chambers (especially 671's) are pitted and sometimes holes have been eaten through the metal. Another dangerous reason is when melted by the bulb it stays in a hot, corrosive liquid form until cooled and if a child picked up the locomotive and turns it over and spills on his hands..... I'm sure it probably happened. The SP pellets when melted would absorb into the liner in the bowl, no spilling. Plus breathing in the nitrate vapor can't be good.
