During the arduous tunnelling process of the Glasgow Subway, which took place over five years between 1891 and 1896, accidents were alarmingly common, with a number of workers fatally injured or badly maimed.
The most serious accident on the unbuilt subway occurred on April 15, 1893 when a large explosion rocked Great Western Road.
A gang of men had been digging a shaft when an accumulation of gas suddenly ignited, hurling them through the air.
