There is a Braehead in the appropriate location with several mining and claypit works indicated on the 1898 Ordnance Survey map. The exhaustive mines and minerals website Aditnow does not show a coal pit of either name in this vicinity. The southern terminus of the line must be Braehead. The pit there was considerably extended and the Drumpeller had many additional stub branches at the southern end as well as nearer the canal terminal. General The railway opened on 3 March 1845, and it had the track gauge of . The canal at Cuilhill Gullet was on an embankment above the local ground level, and the railway approached on a viaduct and crossed to the north side of the canal. The main line of the canal was diverted to the north of the wharf, forming an island. By 1849 the railway was sending 90 boatloads of coal a year to Glasgow. In 1849 an extension to pits at Tannochside opened. The land falls considerably from Cuilhill to Braehead – about 100 feet in a mile (20 metres in 1 km) – and Cobb shows two inclined planes in this short section of railway. It seems that the originally planned extent of the line was not completed in 1845: Braehead is only from Cuilhill; in 1847 the line was extended to Tannochside, and this may be the originally intended southern terminal. The line ran south-south-east from Cuilhill Gullet (just east of where the present-day M73 crosses the line of the canal) along the line now occupied by Langmuir Road, then curving south-south-west to where Aitkenhead Road roundabout is now. Evidently the Monkland Canal Company exercised the power to acquire the Railway Company, and with the changes of ownership of the canal itself, the Drumpeller Railway became the property of the Caledonian Railway (CR). The CR changed the track gauge to standard gauge during June 1872 in association with making a connection of the hitherto isolated line to its own network. The connection was a west-to-south curve at Bargeddie station on the Rutherglen and Coatbridge line, giving rail access from the pits. The pits the line was built to serve were eventually exhausted and the line closed in 1896. Gartcraig as original western extremity As described earlier, under James Watt's supervision the canal stopped some distance short of Glasgow. Hutton's description of the exact location is the clearest: "The terminal reached by
