I enjoyed reading Adrian Garner's book "Monorails of the 19th Century." I discovered from it that the first rail link between what was at the time Port Kampala and Kampala itself in Uganda was a monorail!
Rolling stock was propelled along the line by bullocks rather than any form of mechanical propulsion.
The line was less than 8 miles long and lasted no more than a few years.
These are the details:
