 Subsequent links were added southwards to via the Alloa Railway in 1889 and northwards to Tillicoultry from 1851, where an end-on junction with the Devon Valley Railway was made some years later.The network was finally completed in 1906 with the opening of a second line to Dunfermline via Kincardine and Longannet along the northern bank of the Forth estuary.This carried a passenger service until July 1930.
