 The powers to build the Slamannan and Borrowstounness Railway were transferred to the Monkland Railways at the same time.When there was a reconciliation, it was proposed that Slamannan trains for Bo'ness should use the now-completed Slamannan Junction line from Causewayend, joining and immediately leaving the E&GR line and descending to what became Bo'ness Lower Junction.At a stroke this would save the cost of constructing the "low level" line from Causewayend, with its civil engineering challenges in crossing the Union Canal, the viaduct over the low ground south of Whitecross, and the bridge under the E&GR near Myrehead.
