2AE. Humber Bridge Road, Grimsby, Lincolnshire With thanks to Dwight for informing me of these Survivors. Attached to the railway bridge structure are several short cast iron plinth columns with a pattern resembling that used with the 'Moseley' column produced by Revo. Each column supports a swan neck bracket that may have accommodated some sort of tungsten filament (GLS) lantern originally, but more recently, have been fitted with GEC Z8430CMs instead. Additional Z8430CMs (not pictured here) was seen elsewhere on the site, suggesting that they were the standard lantern used by the Port of Grimsby in the past.

The first example to be pictured was day burning, revealing that the lanterns (or this lantern, at least) ran high pressure sodium (SON) lamps.

The old installations are supplemented with (or perhaps, superseded by) modern tubular steel columns supporting solar LED lanterns.

The installations appear to have been painted light blue, although much of this has worn off now.

Owing to the size of the control gear components required to run the lamps fitted within the Z8430CMs, separate boxes are strapped around the column bases. The supply cables reach each plinth through a conduit system attached to the outside of the bridge structure, which then terminates into a fuse box. As the railway passes beneath the bridge at this point, accessing the fuse boxes would not be a straightforward task.

The use of main road lanterns for such short columns seems unusual, though if the Z8430CM was the standard lantern of the Port at the time, their use is understandable.

Two further installations were to be observed above Murray Street.

The control gear boxes are also GEC products.

All of the glass bowls are intact and secure to their lanterns.

The final plinth light had the office complex for Young's Seafood as a backdrop.
