I came across this when looking into early railways. ...
Ivan Kirillovich Elmanov (Russian: Иван Кириллович Эльманов) was a Russian inventor. During 1820, in Myachkovo, near Moscow, he built a type of monorail described as a road on pillars. [3] The single rail was made of timber baulks resting above the pillars. The wheels were set on this wooden rail, while the horse-drawn carriage had a sled on its top. [3] This construction is considered to be the first known monorail in the world. [5][6] The horse-drawn carriages travelled on an elevated track. One project envisaged using them to transport salt on Crimea. [9]
Russia was a pioneer in the design and construction of monorails, from early horse-drawn models to later electrical and magnetic levitation systems. [2] Sadly, Elmanov could not find investors to fund for his project and stopped working on the monorail. In 1821, Henry Palmer patented his own (similar) monorail design in the UK. [2][3]
