… Work was divided into six sections; access to each was via a 25 foot (7.6 m) diameter ventilation shaft, which ranged in depth from 70 feet (21 m) at the eastern end to 300 feet (91 m) towards the western end.Candles provided the only lighting in the workings and were consumed at a rate of one tonne per week, which was equalled by the weekly consumption of explosives.Once the eastern section had been blasted out, it was cut to form a gothic arch and left unlined.The restrictions imposed by the site contributed to a delay in the tunnel's completion. Most of its 118 miles were either level or had gradients no steeper than 1 in 1000. Construction started in September 1836 - opened in June 1841. Box Tunnel. During the post-war years, portions of the ammunition depot were redeveloped for other facilities, including the Atkins.…full illumination [of the tunnel profile] can occur on April 7 in three (non-Leap) years out of four, whereas in a Leap-Year this should occur on April 6.
