Blenkinsop's rack locomotive, 1812. Model (scale 1:8). The locomotive represented here was designed by John Blenkinsop (1783- 1831). Blenkinsop worked at Middleton collieries near Leeds and devised a rack and pinion system. This consisted of a cogwheel on the locomotive which locked into special teeth in a rack on one side of the rail. This was particularly succesful in mountain railways. 3/4 side view front rear.
