This plaque commemorated the Subway below the River Ely. I recall that it was fixed upon the wall of one of the entrance buildings against a ceramic tiled dark green border with a white background. As my memory fails me, can anyone confirm which side of the river it was placed? The text of the plaque states :

This Subway.
Constructed under the express Authority of Parliament
(59 & 60 VIC. CAP. 233)
By The
Taff Vale Railway Company,
Was Commenced on the 5th July 1897, and Completed and
Opened for Public Traffic, on the 14th May 1900.

Many thanks to David Ings, [655] the Welsh Railway Research Circle [737] and myself for deciphering the text!
