Underneath the new white box is a TPWS buzzer, the new open boxes are probably for the new door locks (magnets) and above is the fire bell. Stuart Mackay.

7th October 2010

Set number: 121020

I have always had a soft spot for the single unit "bubble" cars that used to work branch lines; indeed my first ever train ride was in one of these when they worked the Stratford-upon-Avon to Leamington Spa shuttles. One of the remaining class 121 units in still in regular service for Chiltern Railways and 121020 was booked to run from Aylesbury to Kidderminster (SVR) on Thursday 7 October 2010 where it is due to perform at a gala over the coming weekend. I think that the blue colour scheme carried by this unit is most attractive so went to a bubble-sized spot on Hatton Bank where I knew that the sun would be in just the right direction at a little over 14.00. Just after I arrived, 66154 ran into the Down Goods Loop with 6M48, the 10.02 Southampton to Bescot loaded train of Ford cars. I took this to mean that 55020 was close behind and indeed, it appeared no more than two minutes later. Peter Tandy.

I was at Hatton North Junction waiting for a northbound freight on 28 April 2016 when a fellow photographer told me that Chiltern single unit 121020 was coming south within the next few minutes working from Tyseley to Aylesbury. After a swift move from the field to the footbridge the newly repainted bubble car appeared under the Shrewley Road bridge and stopped at the up line signal to allow a Chiltern Railways train from Stratford-upon-Avon to leave Hatton station for Leamington Spa. A longer lens might have been a better bet for this shot given that there is no scope here for a more broadside view but I had only the one piece of glassware with me on this occasion. Peter Tandy.

Set number: 960014

I was just in the process of grinding some beans for my coffee on 16 September 2015 when a friend 'phoned urging me to get over to the Hatton area as soon as possible because 960014 (977873) and 55020 were heading north from Aylesbury to Tyseley and were already near Fenny Compton. Having always been a fan of single car DMMUs I grabbed my camera bag and drove over to the 3 arch bridge in Dark Lane, Hatton. As soon as opened the car door I heard a train coming and just had time to take my camera from its bag and grab a rather unsatisfactory shot without checking any camera settings and without noticing that it was set to manual focus after taking some astronomical photographs a few nights ago. The shot is just about acceptable as it shows the rare sight of two "bubbles" in the Down Goods Loop. Peter Tandy.

Date: 16th September 2015

Set number: 960014

The single car DMMUs running as 5T00 from Aylesbury to Tyseley on 16 September 2015 weren't booked to stand in Hatton DGL but rather to wait for their path north in platform 3. Through early running it had to routed along the loop because a train from Stratford-upon-Avon, 1H47, had no choice but to use that platform for the scheduled station stop. After the Stratford train had gone south and 3 trains had gone north 960014 + 55020 were allowed to leave the loop and resume their journey. It was a bit of a shame given the sunny conditions that they were routed through the branch platform but it was fortunate that some trees cast a complete shadow over the line thus avoiding an unpleasant shot in contre-jour. This is far from being 960014's first trip along here; I photographed it in the area on at least 3 previous occasions including on 23 June 2008 when it was running a timing trial before WSMR started locomotive-hauled operations.
