One of the stranger model train cars sold by Lionel is its "Toxic Waste Car," which it introduced in 1956 . From the product info:
Congratulations! Your Lionel railroad has won the government contract to safely remove toxic waste from your friendly local nuclear power plant for transport to remote dump sites located all across the continent. The simulated toxic waste load is held in two containers from which an ominously radiating light flashes on and off whenever the track is energized.
Over the years, Lionel has made various design changes and tweaks to the Toxic Waste Car. For instance, in 2007 it turned it into the "Area 51 Alien Radioactive Flatcar."

Jan 1993: In order to find out how close workers could safely stand by the tracks while the new high-speed trains were going by, British Rail announced it would conduct an unusual experiment. It would tether employees to wooden posts located around six feet from the tracks and then measure the force of the slipstream on them as the trains went by at 140 mph.
Although members of the public weren't invited to participate in the experiment, about 50 of them volunteered to be guinea pigs anyway.

Sunday London Telegraph - Jan 31, 1993
It was difficult to find out the results of the experiment, but after some digging I located a postscript printed in the
Magazine of the Pennine Railway Society. The test never took place. Faced with widespread criticism, British Rail's Health and Safety Executive cancelled it.
Loco Notion
Barmy BR proposed to tether workers to trackside posts as high-speed trains thundered past at 140mph. Bosses wanted human guinea pigs to stand as close as 6ft 6in to the expresses to test the effect of their slipstream. Rail
union chief Jimmy Knapp branded the idea barmy and suggested BR use Transport Secretary John MacGregor instead.
The workers would have been attached to posts by special harnesses that would allow them to move to the side but not forward. They would have been asked for their reaction after the trains had roared past. The tests would have helped to determine the distances from trains at which staff could work in safety. They would have taken place between York and Darlington.
However the Health and Safety Executive banned the scheme. The tests have been postponed pending further discussions to see how BR could get the information another way.
One disgruntled railwayman described the scheme as harebrained and said he joined BR to drive a flipping engine, not to play flipping bondage games. However a number of civilians have volunteered to take part in the scheme, preferably dressed in leather and chained from head to toe.
The effect when someone stands in the slipstream of a high-speed train is likely to be they'd get sucked under it. If tied to a post perhaps it would suck their boots off, or maybe they'd go blue in the face.
The idea is on a par to that of abolishing the timetable to stop the trains running late.

Just as exciting as it sounds!

In 1967, Dragan Petrik was granted a patent (
No. 3,343,495) for a high-speed, rocket-powered train that would run on blocks of ice. In an Oct 1967 column, NY Times reporter Stacy V. Jones provided some details:
From South Africa comes a proposal for railroad trains to run at high speed on blocks of ice instead of wheels.
Dragan R. Petrik of Pretoria was granted a patent last week for vehicles equipped to change the blocks as they melt and wear down, without stopping the train.
Patent 3,343,495 provides for propulsion by jet, rocket thrust, propellers or other means independent of the usual wheel traction. While conventional rails could be used, Petrik prefers a flanged metal surface that can be heated in cold climates.
Each car is to have cold rooms for storage of the ice. Blocks are to be forced down through ducts under control of a sensing unit that maintains the car at proper height.
Conventional wheels may be used in a station or for emergency support. A set of ice blocks is provided just ahead of and in back of each set of wheels. One ice skid can be used while another is being replenished.
For braking, there is a rubbing surface along the track, on which friction pads can be applied.
Petrik says his system will make possible very high speed for all types of land vehicles.
I have no idea if this would work, but it would be interesting to see it tested out.
In the early days of rail travel, people who had the financial means to travel first class often went third-class, to save some money. To discourage this practice some British railway companies adopted the "soot-bag system". They would hire a chimney sweep to travel in the third-class carriage and shake out the contents of his bag, getting everyone dirty. At other times, pigs and sheep were transported in the third-class carriages. The idea was to make third-class travel as unpleasant as possible.
I figure that the modern-day equivalent in the airline industry is the "no-legroom system" and the "only-a-bag-of-peanuts-on-a-five-hour-flight system".

But another and apparently unforeseen consequence [of the introduction of third-class railway carriages] followed, that "certain persons in superior positions" were base enough to travel in third-class carriages. If universal indignation could have crushed these miserable creatures, they would soon have succumbed; but they persevered, even in spite of the "artificial inconveniences" specially invented to deter them. Not but what these inconveniences were serious enough.
The management of the Manchester and Leeds Railway adopted what was known as the "soot-bag system." Sweeps were hired to enter a third-class carriage which had been specially kept for the benefit of "persons in superior position," and then shake out the contents of their bags. At other times, if a correspondent of the
Railway Times can be trusted, "sheep and sometimes pigs were made the substitutes for sweeps."
Even then some persons—if report said true some bailies of the City of Glasgow—persevered in their evil courses. But their conduct was strongly reprehended by all respectable persons.
