I believe the "fleet refurbishment list" thread has now been closed so I have created a new thread as there has been some recent news on this topic. Between 2010 and 2015 86 out of 90 metrocars were refurbished at Wabtec Doncaster. This work included corrosion repair and interior modifications including improved wheelchair and pushchair access, two tone flooring and a new door closing tone. This refurbishment work has helped to extend the life of these metrocars and made them compliant to PRM regulations. 4 metrocars, the two prototypes 4001 and 4002, in addition to 4040 and 4083 were never sent to Wabtec and never received this refurbishment. It was believed at the time that these metrocars would see only limited use for special events and at busy periods such as Christmas however this has not been the case. These unrefurbished metrocars did not have any corrosion or interior PRM work carried out. Reliability problems with the fleet, the time period until the new rolling stock arrives and also the upcoming PRM deadline, as unrefurbished metrocars do not meet PRM requirements, has meant that it has now been decided to refurbish these 4 metrocars. I do have some gaps in my knowledge of this but I will provide everything I know. The refurbishment is being carried out at Gosforth depot rather than Wabtec and will be slightly different to the Wabtec refurbishment. I do know that this refurbishment consists of door modifications and corrosion repair however I am unsure if there is any changes to the interior layout during the refurbishment. Metrocar 4040 has spent approximately 12 months having this work done at Gosforth depot. It has now returned to service and was seen today (August 8th 2019) operating the 18:03 from Pelaw to Benton. (I did not board myself but I am almost certain that this is the correct service). I did see them at the correct time at Four Lane Ends with Benton on the front. It now has the new black and yellow livery and was seen paired with 4083, which is yet to have any work carried out and is still in Emirates livery. If anyone has been on metrocar 4040 today or does so before I get the chance, it would be good to know what changes have occured to the interior. I do believe that this will be less extensive than the interior changes done by Wabtec. From what I understand, 4040 needed extensive corrosion repair done which explains the long time scale of work. I am unsure whether 4001 and 4002 have already had this work done or not. If this work has occurred, refurbishment of 4001 and 4002 may be quicker. 4083 has not yet has corrosion repair done so will take longer. With 4040 complete, I believe 4001 and 4002 are in progress with 4083 yet to start. I assume that these 4 metrocars will still only be able to operate with eachother after this work. If anyone knows anymore about this, it would be good to know. Do look out for 4040 and 4083 on peak services as it would be good to see the interior changes on 4040.
