Meanwhile, a number of short lines were built for specific purposes. Among these were the Mansfield and Pinxton and the Leicester and Swannington. The Mansfield and Pinxton was a feeder for a canal and was a wagonway, but these short lines were pivotal in later events. Possibly the longest was the Cromford and High Peak Railway, opened in 1833, to connect the Cromford Canal with the Peak Forest Canal. It attracted interest because it provided access to Manchester through the Peak District of Derbyshire, even today an obstacle to transport.
