A Trolleybus under the bridge at Grangetown Taken in July 1970, this photo shows a Sunbeam F4 trolleybus 4 (GAJ 14) with Roe 61-seater bodywork on a private tour of the area's trolleybus system going under a railway bridge in Bolckow Road near the junction with Eston Road. This bridge carried the Bolckow Vaughan Private Railway to the Dorman Long steelworks nearby, but has long since been dismantled and the whole area is completely different today.
