Amalgamation
Seeing themselves to be suffering the same disadvantages as well as being small concerns now that large railway companies were increasingly being promoted, the M&KR, the Ballochney Railway and the Slamannan Railway decided to amalgamate, and they did so on 14 August 1848, forming a new company called the Monkland Railways.
The Monkland Railways company was absorbed by the Edinburgh and Glasgow Railway by an Act of Parliament, dated 5 July 1865, effective from 31 July 1865. A day later (on 1 August 1865) the Edinburgh and Glasgow Railway was absorbed into the North British Railway.
