northern Derbyshire, is the only one Thompson's station buildings to survive largely as-built and is a grade II* listed building. Notable for his criticism of the extravagant nature of the railway architecture of the day, Whishaw nevertheless praised Thompson's works in Derby, writing: The admirably contrived and elegant roofs, the spacious platforms, the great length of the whole erection extending to upwards of a thousand feet. All unite in rendering it the most complete structure of the kind in the United Kingdom or perhaps the world. Thompson and Stephenson went on to work together on the Chester and Holyhead Railway, for which Thompson designed the architectural elements of the Britannia Bridge over the Menai Strait as well as the Italianate Chester railway station, the frontage of which closely resembles the original station at Derby. The bridge was largely destroyed by fire in 1970, though Thompson's masonry work was incorporated into the rebuilt structure. Among his other works on the line were the stations at Holywell Junction, Flint, and Mostyn (now disused), Conwy, and Bangor. Thompson was also the architect on the Conwy Railway Bridge, including making the towers castellated in order to match the nearby 13th-century Conwy Castle. The Britannia and Menai bridges both used Stephenson's pioneering tubular design. Cambridge railway station, along with Great Chesterford and Audley End on the Eastern Counties Railway, were initially credited to Sancton Wood but are now believed to be the work of Thompson. Canada again Thompson remarried in 1840. His second wife, Elizabeth, died in 1852, and on 30 June 1853, he married Mary Ann Groves, from Wareham, Dorset. The couple sailed for Canada, and Thompson took up employment with the Grand Trunk Railway and the St. Lawrence and Atlantic Railroad. He designed Union station in Portland, Maine, which was claimed to be the largest station in America when it opened in 1855. He also designed the masonry for the Victoria Bridge in Montreal, another Stephenson-designed tubular bridge, as well as multiple other stations (St. Marys Junction station c. 1858) and railway workshops. The Thompsons returned to London in April 1859. In 1866, he retired to a house he built in Hastings in Sussex, before finally moving home to Bredfield in Suffolk, where he died on 23 April 1895. He was buried in the local cemetery. Although well paid during his career, retirement rained Thompson's wealth and he died in poverty without leaving
