As a result, Mid Calder was served by a station at Kirknewton, three miles away which was called Mid Calder until 1982. This meant that adapting to the loss of its traditional sources of income could have been difficult for the village. But at precisely the right moment the world's first oil boom occurred, in West Lothian. This was based on oil extracted from shale, and by 1870 over 3 million tons of shale were being mined each year in the area around Mid Calder. Output declined with the discovery of liquid oil reserves around the world in the early 1900s, but shale mining only finally ceased in 1962. The "bings" that characterise oil shale mining elsewhere in West Lothian have largely been flattened around Mid Calder and the land reclaimed for recreation, industry and housing.
