sentences:  At the start of 2013 DSB also used one-man operated trains on the two small regional rail lines Svendborgbanen and Aarhus nærbane.As a result of several years of major annual deficits, DSB started implementing one-man operation on several rail lines on 29 June 2013.This led to reductions in staff, followed by widespread protest and some small illegal strikes by train drivers, who accused DSB of using rolling stock which was unsafe for one-man operation.
