Derby's Street Lighting PFI Contract

Broadway, Darley Abbey - Part One

The outgoing lighting on this road largely consisted of various 90 W SOX lanterns fitted to 25 ft and 8 m tubular steel columns. The relighting brought an end to almost 80 years of 90 W SOX (and its predecessor, 140 W SO/H) operation along this road - photographs exist of the road as it appeared in the 1930s and 1950s, and the original lighting along here consisted of 140 W open fittings installed in the centre of the carriageway, by means of enormous outreach brackets. This scheme appears to have lasted until the 1960s, when the majority of the columns due for removal under the PFI relighting scheme would have been installed. Broadway is a tree-lined road, and so most of the new 10 m tubular steel columns are fitted with outreach brackets, in an attempt to move the lanterns away from the overhanging tree branches. Incidentally, the new lanterns are the SGS 253 (medium) version of the Philips Iridium, and run Cosmo-White lamps.

The following photographs were taken on Sunday, 8th August 2010.

An integrally-geared Philips MA 90 lit the entrance to the Broadway Public House car park. This was installed in the early 2000s, when St Mary's School opened in the area. Notice the PFI-standard twin aspect speed limit sign in the foreground; the signlights are Simmonsigns LUAs, with LED lighting units.

Another MA 90 followed; the replacement column here was squeezed in between two trees. The 'T' marking on the outgoing column is likely to stand for 'Transfer' - this refers to the electrical connection works required: rather than having the supply disconnected and a new service connected to the replacement column, the service would be transferred to the new column. Generally, this is cheaper than disconnecting the supply to one column and providing a new service to the replacement column.

A similar setup was next, although this MA 90 had been fitted with an anti-glare shield, despite its proximity to the adjacent tree. Of course, the tree would only offer effective light blocking in summer; once its leaves had fallen away, there would be an increase in back spill. The replacement Iridium was not fitted with such a device, although time will tell as to whether this remains the case. (By the way, the picture was definitely meant to look "arty", and was not taken from this unusual angle due to the tree or, indeed, the position of the sun at the time of photographing!)

A convenient clearing on the right made for a useful new column location in the next installation:

The next MA 90 sported a Royce Thompson SC 1000 photocell; the same as is fitted to all new lanterns being installed on the PFI.

The next outgoing column was a Stewart and Lloyd that probably dated from the 1960s' lighting scheme. Again, an MA 90 was fitted, although I think that this one dated from the 1990s.

This time, the type of outgoing column remained the same as that seen in the previous couple of photographs was, but now (at last!) there's a change of lantern - a 2000s' Thorn Alpha 4 was seen here. The wood pigeon must have preferred the outgoing column to the new one as well! Broadfields Close can be seen in the background; by the time that these photographs were taken, the outgoing columns installed along there had been removed.

Back to MA 90s now...and trees!

Finally, a lesser-spotted Thorn Alpha 1 appeared, again fitted to a Stewart and Lloyd column. These lanterns are fitted with two-part cell detectors.

The outgoing column doubled up as a bus stop. Owing to there not being a new column installed here, a short straight post was installed, in order to support the bus stop sign.

Despite being surrounded by tree branches, the Opticell on this Alpha 1 looked reasonably clean.

Two further MA 90s were installed after the Alpha 1; the first was not installed within trees...

...the second most definitely was...

...although not as badly as this Thorn Alpha 8 was!

The pigeon seen earlier perhaps did not like Alpha 1s, however, as this example had a particularly grubby Opticell unit!
