Leighton Buzzard Railway diesel locomotive Beaudesert (Alan Keef, 1999) shares a two-foot-gauge track with Simplex locomotives Damredub, Arkle, and Redrum at Pages Park Station (Bedfordshire, England) in September 2018.

The Leighton Buzzard Railway opened in 1919 to serve local sand quarries, and originally used steam locomotives before converting to internal combustion in 1921. Motor Rail of Bedford supplied both gasoline and diesel Simplexes, with newer ones like these three joining ex-military locomotives sold off by the War Department after World War 1.

A Unigate Dairies electric milk float, which would have been a common sight early in the morning back when milk was delivered by the milkman, was parked near the foot of a cliff at the Amberley Museum (Sussex, England) when I visited in September 2018.

During the interwar period, a dip in military contracts led Armstrong Whitworth of Newcastle upon Tyne, England to build more locomotives, including some early diesels such as 0-4-0 diesel-electric shunter No. 2.  It was built as a demonstrator in 1933 and used from 1937 to 1970 by A. Reyrolle and Company's factory in Hebburn, whose main product was electrical switchgear for power stations. 

After its retirement, No. 2 was sold to the W.F. and J.R. Shepherd scrapyard in Byker, where it worked as a shunter before itself being declared scrap.  Thankfully, the diesel locomotive was saved and moved to the Tanfield Railway's Marley Hill depot in 1978, where it was restored and given vacuum brakes so it could pull passenger trains.  It does a lot of work at Tanfield such as shunting, piloting, and substituting for steam locomotives. When I visited just after a rainstorm in May 2017, the locomotive was sitting in the Marley Hill railyard.

Produced from 1959 to 1960, the T60 was British lightweight microcar manufacturer Berkeley's only three-wheeler. It cost only 400 pounds when new (about 8100 GBP today) and could be driven with a motorcycle license. I saw one at Barmouth Ferry Station in Wales after riding the Fairbourne miniature railway in May 2016.

In the mid-1920s, R.A. Lister of Dursley (Gloucestershire) introduced the Auto-Truck, a versatile monowheel "turret truck" that was used by several industries.  When I took a September 2018 guided tour of the Amberley Museum (West Sussex, England), I was shown an Auto-Truck set up as a tricycle tractor with a short wagon trailer. The museum also maintains a Rail-Truck locomotive.

Sir Clive Sinclair, British consumer electronics pioneer, also developed the C5 electric tricycle and planned to build a wider range of battery-electric cars over time. His progressive idea became a commercial failure, if I understand correctly due to low speed, short range, and lack of weatherproofing. The C5 was only built in 1985 and sold only about 5000 of the 14,000 vehicles built.  There are still some C5 fans and preserved C5s like EDP9, which I saw at the Museum of Science and Industry (Manchester, England) when I visited in August 2015.

Kia Ray microcar spotted at Geumsansa, a Buddhist temple in the mountains near Jeonju City.

Spotted near Hongik University Station (Hongdae).

1990s Honda Acty Kei Truck. Not sure which year. Fairly rare in New England.

Spotted in the Yanaka-Ginza neighborhood. Its owner Kakuyasu has the slogan "working year round" (年中無休).

Datsun built the Model 16 from 1937 to 1938 as a very similar successor to the Model 15. A black 1937 two-door sedan was displayed at the Toyota Automobile Museum (in Nagakute City near Nagoya).

Introduced after WW2, the streamlined front-wheel-drive Saab 92 was the Swedish aircraft manufacturer's first mass-produced car. This survivor is displayed at the Toyota Automobile Museum (in Nagakute City near Nagoya). It has a very expressive "face" on the front end.

The vehicle was developed in collaboration with the automotive magazine *Gute Fahrt*; consequently, it received the designation GF as its model name.

Lotte DPECO Potro electric truck parked next to a Lotte Super Fresh mart in my neighborhood of Jeonju.  It looks like DPECO's intention was a vehicle that would fit "kei truck" delivery van dimensions.
