1914-1924 Rail Cruisers/Draisines

[World B4]

I would like to learn more about rail cruisers (also called motorwagons) and armored draisines from the period of 1914-1924. For those unfamiliar, a rail cruiser is an armored train car that has it's own engines and armament and can operate independently, though they could also be used in regular armored trains along with other cars. Armored draisines are smaller, lighter variants of the same concept, typically only having a single small turret if any.

They were pretty diverse in the 1930s and 1940s, but rare during World War 1, when the armored train concept really took off. I am only aware of 2 at the moment, those being the famous Orlik/Zaamurets of Russia->Czechloslovak Foreign Legion, and the less well known Austro Hungarian Motorkanonwagen.
I made this thread to hopefully learn about more from this time period.

In 1917, Bolsheviks armored a city tram, though it's arguable that reliance on electric wires could eliminate this vehicle from the "self-propelled" requirement.

According to Landships II, several Putilov-Garford armored cars had their road wheels swapped for rail wheels in the 1920s, I would love to narrow down the year when this happened.

Some Irish draisines made by swapping armored car wheels in the civil war period.

And I shouldn't forget the conceptually similar Blinado Mack de Pacho Villa from Mexico's civil war peroid.

I had forgotten, a distinctive looking Benz prototype armored car tested in Russia in 1912 was designed with the ability to be converted to a railcar

Early armored draisines with 2 armored maxim gun turrets were made in Russian Ukraine during WW1

Russo-Balt armored cars were converted to armored railcars in WW1

In Russia, similarly armed armored draisines of the "Matval" model were made during the Russian Civil War.

I am in particular interested in the armored railcar produced by Izhora in February 1920 with a singular turret armed with a 37mm Hotchkiss gun, with 4 Maxims in side mounts, and an armored draisine produced in Kiev by the 4th Company of the 2nd Trans-Amur Railroad Battalion that had 4 high angle turrets with Colt 1895 machine guns. I have not seen any photographs of either and I would love to.
