The L&YR was one of only four pre-grouping railway companies to design and manufacture its own signalling, the others being the LNWR, the Midland and the GWR.
The RSC continued to supply signalling equipment to the L&YR as the huge volume of work was more than the railway company could cope with by itself. After the turn of the century, however, this volume of work tailed off and the L&YR became more self-sufficient.
In 1900 the L&Y became the first company in the UK to install power signalling when the Westinghouse company resignalled the junctions north of Bolton station. This was later followed by a major scheme at Southport.
The training of signalmen improved from 1910 when the Signalling School was opened at Manchester Victoria complete with a model railway layout which is now preserved at the National Railway Museum in York.
