  • 999600 & 999601

    20 June 2004 - Tom Walker

    At first glance this is a converted class 150- but think again. 950001 was actually purpose built using the same design as the 150- simply because this is cheaper than designing a whole new unit.

    Almost certain this is the unit I saw standing on the line from Longannet P.Stn to Kincardine at around 10.00 hrs 1/8/06.( Unless there is anything else that looks like it's been converted from a class 150/1!)

  • 999600 & 999601

    8 March 2008 - Greg Sherlock

    Saw it at Doncaster West Yard when leaving at 15.45. This unit seems to visit the Doncaster area quite regularly. Any particular reason why?

  • 999600 & 999601

    16 April 2008 - Jamie Rowley

    I saw this unit passing through Chesterfield, Derbyshire on the 10th May 2008 heading towards Sheffield. The unit crossed over to the good line after passing through the station, which has been recieving much work over the last few months.

    Sorry, I ment 11th April! I got the wrong date off my travel ticket!

  • 999600 & 999601

    17 April 2008 - Bryan

    It was built at York as an add on to the then current 150 unit build.

    It has always been a recording unit. I have travelled on it for work around the Yorkshire area. Quite entertaining when it pulls into a platform and members of the public have to be turned away. When you are sat having a mug of tea.

    11 June 2008 - Dave Shell (NREL, AVRP, OTPPG)

    Please note that the above trains probably won't now run as the TRU has gone back to Derby with equipment failure. Hopefully, the TIC might come out later in the week to recover the track recording. If it does it would be top and tailed by 2 locos, probably 31's.

  • 999600 & 999601

    8 March 2016 - Jon Horswell

    IMO this was the best livery that this 150 has carried. Now after its recent refurbishment it has large magnifying glasses applied to the bodysides as part of its new branding.

  • 8 March 2016 - John Manchester

    Does anyone know what refurbishments have been carried to these two vehicles? Any additional equipment or just a cosmetic upgrade?

  • 8 March 2016 - Jon Horswell

    I think that the bogies and engines have been refurbished, so it seems to be nothing more than a general upgrade though someone will know for sure. How long was it out of traffic for?

  • 9 March 2016 - Rich Mackin

    Last sighting recorded here was back in September 2015.
