In 1969 with the introduction of the Power Schemes at Derby and Trent, a number of mechanical boxes were retained to control level crossings or complex pointwork in a concentrated area thus saving money on point machines - these became "Shunting Frames".

With the increaSe in technology, CCTV crossings eliminated quite a number, plus dwindling freight traffic rendered more redundant.

Thus in 2006 only three are regularly used and plans are well advanced for their demise.
Stapleford and Sandiacre signalbox was opened on September 4th 1949.  In connection with the Trent Power Scheme it was downgraded to Shunting Frame status as part of stage 2b on 19th October 1969.  It was abolished under Stage 2A of the East Midlands Signalling Renewals on 9th October 2009.

These three Trent signals protect Sandiacre Sf and must be at danger before trent can give the releases.  Although they are plated as Trent signals and Trent controls the SPT's, Sandiacre can actually set routes from all three.

Stanton Gate box was constructed in connection with the Trent Resignalling scheme and opened as part of stage 2b on 19th October 1969.  Originally classed as a block post it contained the Tyers No.6 tablet instrument for the Mapperley branch working to Stanton New Works.  The box finally closed on 24th June 2006 having been out of use for the previous four years.

Empty steel coil wagons are seen passing Lock Lane being hauled by 60059 as 6V92 Corby BSC - Margam.  Normally running via Leicester and Hinckley the train was diverted because of a points failure.

An unusual pairing of 60002
An unusual pairing of 60002 "High Peak" and 60001 "the Railway Observer" heading 6K50 Toton Old Bank - Crewe Basford Hall pass Lock Lane with a train consiting of empty 'Falcon' wagons. this train is routed via the South Staffs line and the WCML.
Lock Lane signal box opened in 1957 replacing a Midland structure.  It is a LMR type 15 and was the wonder of the modern age when built as it contained an inside toilet....  It became a shunting frame with Stage 1 of the Trent resignalling scheme.

Originally a 20 lever LMR Standard frame, it was shortened to 10 levers with just 5 working when changed to a Shunting frame.  Curiously the first five levers are unnumbered with the second five numbered 1-5.

Having become rather delapidated Lock Lane was completely refurbished in 2005 and now looks very smart.  new windows were installed in sympathy with the original style.
