 The actual decision to start was taken at another shareholders' meeting on 28 September 1849—still omitting the "low level line".Contracts for building the line between Myrehead and Bo'ness were let to John Barr & Co in October 1849, the works to be finished by April 1851.While the work proceeded satisfactorily, the Directors now reconsidered their decision to run trains via the E&GR at Myrehead.
