The gauge war
In the so-called "gauge war" ("gauge war"), the GWR fought fierce competition with the London and North Western Railway (LNWR). In 1846 the Bristol and Gloucester Railway was bought by the Midland Railway and converted to standard gauge in 1854. Three- rail tracks were laid on this route , on which trains of both gauges could run. Plymouth was reached in 1849 and Penzance in 1867 on the south-western tip of England with other own line structures . The South Wales Railway was opened in 1850 and connected to the GWR by the Wye Bridge built by Brunel in 1852 and Birmingham with Snow Hill station in the same year . Through such takeover and further line construction, the GWR grew to the largest company in the south-west of England.
The South Wales Railway was entrusted with the operation of the Carmarthen and Cardigan Railway , which today is only in operation on small sections: the bankruptcy administrator did not cease to operate until 1878. In 1872 the line was converted to standard gauge . Today the Gwili Railway operates on a section of the route near Carmathen and the Teifi Valley Railway museum railway operations on a section near Henllan .
