this point the Liverpool and Manchester Railway, which has its passenger terminus at Lime Street, a mile and a quarter from Edge Hill, is joined by a branch railway running round the city, to the docks at the north end, and also by branch lines running through tunnels, under the city, to the various goods depots at Wapping, Waterloo, and Crown Street, so that it will be easily perceived that as regards goods traffic, Edge Hill is a very important and busy place indeed. This is sufficiently proved by the fact that, at the present time, no less than 534 trains of all descriptions are running in and out of Edge Hill within 24 hours, viz., 273 in, and 261 out, and that it has been found necessary to build there a steam shed or engine-house, which holds eighty engines.

On the other hand, the trucks loaded at all the depots have to be sent, in the first place, to Edge Hill, where they are classified and marshalled in trains for despatch in all directions.

In that year (1873) they found themselves
