A Brief History of the Rotary Snowplow
The first rotary plow was designed in 1869 by Toronto dentist J.W. Elliot. His design, similar to but more primitive than the later Leslie type, was never built. Several other early plow ideas also died a similar death. Some were constructed in prototype form and scrapped, while others never were constructed at all.. These included the Hawley plow, the Marshall plow, the Blake Machine Plow and the Kryger steam snow shovel.
The first successful rotary plow was designed by Canadian Orange Jull. He had the plow built by the Leslie Brothers, owners of a machine shop, and tested it in the winter of 1883-84. The Leslies' soon purchased the manufacturing rights to the plow and went into business building 'Leslie type' rotaries. This is the type of plow most people think of when you say 'rotary.' It has one large circular plow blade rotating on a shaft parallel to the tracks.
Between 1885 and 1903 the Leslies had 62 plows (plus 2 for export) built by several locomotive works. They then sold the rights to the plows to ALCo. However, the Leslies' company exists to this day. From 1905 to 1937 ALCo built 67 plows (plus 4 for export). Two homebuilt, 42 inch gauge Leslie plows were built by Reid Newfoundland. Lima-Hamilton built the last four commercially produced steam rotaries (and the last commercial Leslie types) in 1949-50, under license from ALCo.
Five homebuilt Leslie types (4 diesel, 1 electric) were built between 1950 and 1971. The one plow constructed in 1971, by Union Pacific, was the last Leslie type built. Over the years Leslies were built in US Standard Gauge, 3 foot gauge, and 42 inch gauge, and possibly other gauges for export. Of the 146 known Leslie type plows, there are 41 known survivors, and 5 probable/unconfirmed survivors.

There also were several other types of plows, some successful, some not:
Jull Centrifugal Snow Excavators:
Orange Jull, the inventor of the Leslie type plow, decided to build plows to another design to compete with the Leslies. Between 1890 and 1892, 11 Jull type plows were built. These plows had a large spiral screw placed diagonally across the front of the plow to clear the snow. They were not as good in deep or heavy snow as the Leslies, and never really caught on. All 11 are now scrapped.
Cyclone Snowplow:
This device was invented by E.P. Caldwell. It featured a large spiral screw projecting forward from the body of the plow - imagine a very large tapered drill bit mounted on the front of a boxcar. The only plow of this type was scrapped in 1904.
Bros 'Sno Flyr' and 'Sno Meltr':
These plows were a result of the severe winter of 1949 (see below). The Flyr was a snowblower-type machine, and the Meltr was a snow melting machine. Neither type was particularly successful, and only three were built.
Snowblower-type machines:
In recent years several non-Leslie rotary plows have been built. These plows generally use two large snowblowers, essentially larger versions of a driveway snowblower. These plows are included in this list, but they are more like a highway or runway snowblower than a true railroad rotary plow.

Post-Steam Era Evolution
The winter of 1949 was particularly harsh, and the northern and western railroads were buried in snow. The then-standard steam rotaries proved incapable of dealing with the huge amounts of snow. The railroads looked at several possible solutions to the problem of insufficient plowing ability:

Union Pacific had two large steam rotaries of conventional design built. These were successful plows, but were infrequently used. Both survive today as museum pieces.
CB&Q converted an old steam plow to electric power, using a trailing locomotive as a power source. This proved to be the best solution, and large numbers of conversions followed.
CB&Q, NP and UP sponsored construction of the Bros Sno Flyr, a snowblower-type plow. This plow was superior to the Leslie types in light snow, but could not deal with the heavy, deep snow the Leslies could handle. Because of this limitation, the Bros plows were not produced in great numbers.
In the years following 1949, many steam plows were converted to electric power. Nearly all rotaries now in service are former steam plows that have been converted. Initially most would have been powered by "standard" diesel locomotives that had undergone minimal modifications for the plow-power role. Today, most of these plows get their power from an old locomotives that have been stripped of traction motors and semi-permanently coupled to the plow.
The Burlington Northern (now BNSF) plows are powered by former F9As and F9Bs converted to Rotary Snowplow Power Units (RSPUs). The 10 GP28Ps acquired during the 1990's are equipped to power the rotaries as well, so the RSPU fleet has been gradually declining.
Southern Pacific's converted plows (now part of Union Pacific's fleet) are powered by former F7Bs known as "Snails". These units have their original 16-567B prime movers and the original steam generators, and are semi-permanently coupled to the rotaries. Although the snails and plows originally had matching numbers (MW820x+MW20x), the pairs have been switched around, so the numbers no longer match.
