United Kingdom British Empire (1901)
Draisine – 1 built

Frederick Richard Simms (12/8/1863 to 22/4/1944) is best known in military terms for the rather silly looking ‘Quadricycle Motor Scout‘ of 1899 despite founding a very successful engineering firm in his name. He had been inspired, at the turn of the 19th century, by his knowledge, expertise, and experience in motor vehicles to seek out new business ventures and military contracts were a good source of income if one could be obtained.

He had been born in Germany in August 1863 and educated in Berlin where he met the famous German engineer Gottlieb Daimler. Soon after obtaining a patent from Daimler for his high-speed petrol engines he had moved to London where he founded Simms Motors to make use of this engine. By 1896, he had become a consulting engineer to the newly formed British Motor Syndicate (BMS) and, the following year (1897), a founding member of what is now known as the Royal Automobile Club of Great Britain.

In 1899, he had tried his hand at a military venture combining a small petrol driven quadricycle (known as the ‘Motor Scout’) fitted with a small bulletproof shield and a .303 caliber Mark IV Maxim machine gun and despite proving as a concept that a small machine could be used to move a machine gun around with a high degree of mobility, he received no orders.

The Second Anglo-Boer War was underway by the end of 1899. Fresh from trying his hand at the Motor Scout, Simms turned his eye to helping the British Army. They had entered that war ill prepared for the type of fighting they faced. Large swaths of territory and a highly mobile enemy were hard to pin down and restricting their movements was going to be key to winning the war. Eventually, to pacify the Boers, the British constructed long lines of defenses with blockhouses etc. and it is perhaps because of this that Simms unveiled (in his trademark bowler hat of course) his draisine design to assist in patrolling the railways.

There is little information available on his design which is known as a draisine. A draisine is simply a light auxiliary rail vehicle for moving equipment or people around and the purpose of this one was to move a crew and a machine gun. The diminutive vehicle consists of a rounded ‘bathtub’ shaped armored body which, if it is similar to his subsequent War Car, would be approximately 6mm thick bulletproof steel. Riding on four wheels on the railways and driven by a small 7hp water-cooled petrol engine connected to a three-speed Panhard gearbox the draisine was capable of a respectable 30mph (48 km/h). The machine was open topped and fitted with a single .303 caliber Mark IV Maxim machine gun of the same type (and same shield ) as that from his Motor Scout. Simms envisaged the machine as fulfilling the role of a scout, patrolling the railways and deterring raiders and although it only mounted this single machine gun for his publicity was also to mount a one-pounder pom-pom gun and a searchlight.

Despite managing to cram in 6 men for a photo opportunity at one point, there is clearly no room for a crew of 6 and the suggested compliment was four men.

It is not known what happened to the Simms draisine but he did not patent it and it does not appear to have received any production orders. The photos of him show the machine being tested on a section of line on the north shore of the River Medway and the device is rumored to have been sent to Nairobi. Despite his best intentions his machine was to have no effect on the Boer War or any other war for that matter. Simms was on failure number 2 in terms of military machines although his civilian business was successful. This was not the last military invention from Simms though, more was to follow.

    Were there any conflicts where draisines like this one were used in the fighting? The only one I can think of is the So-Ki from Japan.
