The Mount Holly and Smithville Bicycle Railway - 1892-1898

In 1892, Arthur Hotchkiss received a patent for a bicycle railroad and contracted with the Smith Machine Company to manufacture it. The initial track ran 1.8 miles (2.9 km) from Smithville, in a nearly straight line, crossing the Rancocas Creek ten times, and arrived at Pine Street, Mount Holly. It was completed in time for the Mount Holly Fair in September 1892, and the purpose of the railway was supposed to have been enabling employees to commute quickly from Mount Holly to the factory at Smithville. Monthly commuter tickets cost $2.00. The record speed on the railway was 4.5 minutes, and the average trip took 6–7 minutes. The railway was exhibited at the World's Columbian Exposition in 1893. It only had one track, so it was impossible to pass another rider, and if riders traveling in opposite directions met, one had to pull off onto a siding. By 1897 ridership had declined, and the railway fell into disrepair.

Adjusted for inflation, the $2 monthly ticket is worth $73.40 in today's money.
