By the 1840s improved locomotives meant that Locke was able to build railway lines with gradients as steep as 1 in 50. Locke's success building the Grand Junction Railway resulted in him being offered commissions to build railways all over Europe, notably, the railway between Paris and Rouen. Joseph Locke died in 1860.
