Derby's Street Lighting PFI Contract - Litchurch Lane, City Centre

The equipment being removed consisted of the following items in 1997; given the locations provided for some of the lighting columns, engineers would solely have had to rely on the numbering scheme in order to find individual columns:

Seq. No.	Lamp Number	Location	Lamp Type	Watt	Isolation Point
1	30156	BY RAILWAY	SXPL1	55
2	30157	BY RAILWAY	SXPL1	35
3	30158	OPP B R SCHOOL	SXPL1	35
4	30159	OS B R SCHOOL	SXPL1	35

A 6 m hockeystick column supporting a Philips MI 36 55 Watt SOX lantern was first from London Road.

A Royce Thompson Monostar 1000 photocell was fitted to this lantern.

The new columns are 10 m in height, and are fitted with 'medium' (SGS 253) Iridium lanterns; each running 140 Watt CPO-TW. On the opposite side of the road, a GEC Z9532 35 Watt SOX lantern can be seen attached to a 15 ft tubular steel column.

The Z9532 may have replaced an earlier lantern, running 80 Watt MBF, in the late 1970s/early 1980s.

Another Z9532 followed; its column appeared to be slightly newer than the previous example had been.

A Philips MI 26 was next - this is likely to have replaced a faulty Z9532 in the mid-1990s.

The next couple of outgoing installations retained their Z9532s until the end, however.

A small pool of water had gathered in the lowest portion of this lantern's bowl; suggesting either a leaking canopy or loose gasket.

After this, another older swan-necked column (this time, supporting another MI 26) came into view.

A small amount of the bracket's original light green paint could be seen immediately adjacent the lantern.

The subsequent installation was largely the same, although, a Simplex Aries lantern was fitted here. The outgoing column's inspection door had been secured using a 'Tamtorque' band, and was positioned upside-down.

A 1990s' Hy-Lite HL4N photocell still continued to switch this lantern.

Another column supporting an MI 26 came next.

The GE SOX lamp fitted in this lantern looked as if it had seen many hours' use. Given that the last of GE's SOX lamps were produced towards the end of 2007, this lamp would probably have completed about three years of nightly service by the time that the column was removed.

A replacement column, likely to date from the 1990s, was fitted with a Thorn Beta 5 lantern.

A length of insulation tape secured the Beta 5's bowl. Also just about visible is the small airgun pellet hole on the lower right-hand portion of the bowl. A Zodion SS3DR photocell was fitted here.

Looking the other way, towards the entrance to the famous railway rolling stock factory (the last manufacturer of rolling stock in Britain, as of 2011), two further outgoing columns can be seen.

Yet another MI 26 was first...

...with a second Beta 5 being next. The angular bracket linking the Beta 5 to the column was the only type of this kind installed on the road. The front of a Class 377 'Electrostar' EMU in Southern Railway livery can just be seen on the right in this picture.
