The car was based from a similar design put into service in England on the Liverpool & Manchester; it was 9 feet 6 inches long, by 7 feet 8 inches wide with a 44-inch wheelbase (the wheels were 30 inches in diameter). They featured very low sides around 2-feet in height, just enough to secure barrels of and prevent them from falling off.
