The viaduct was effectively one long continuous bridge, from the southern end of the line to Seaforth. Ths size of the span varied, depending on what was underneath. In these photos, taken near Pier Head, the spans were fairly long to cross main streets.
There are very few people around because the photo was taken on a Sunday morning. The tram is heading to the Pierhead terminus. The "All Cars Outward STOP Here" sign at the left of the picture is now, I believe, in the National Tramway Museum at Crich .
This view, just to the right of the previous picture, shows a rebuilt train approaching.
The decking, to which the rails were attached, and which eventually rusted, was made up of rolled steel sheets. This photgraph, showing the rails, is slightly confusing, because it shows one running rail and one conductor rail of each track.
The rails in the foreground belong to the southbound track (the sun was to the left in this photo). One runing rail of the southbound track is too close to the camera to be seen. The other running rail and its conductor rail are in the foreground.
In the background are the conductor rail of the northbound track, and one running rail very close to it. The other running rail of the northbound track is too far from the camera to be seen.
There are no conventional cross-ties/sleepers. The conductor rail insulators are mounted on blocks of wood, themselves mounted on the deck. The running rails are mounted on longitudinal baulks of timber, fastened to the deck.
The rail-joints are bonded, to provide a return path for the traction current.
