Siemens. Arlington operates and leases the works from St Modwen, Siemens leases 2 roads within the works and this is where the Desiro overhauls are taking place. Kiepe is leasing one of the sheds around the back of the works for the 442 work (the former Electrical test sheds). Incidentally Wabtec's presence has been contract dependant over the last few years, having rented some roads for the FGW Class 143, 153 & 158 overhauls, then left, then returned briefly to the former Van shop for the Southern 455 work a few years ago.
