All of swt units do run with CSR (ex one Desiro set which is running with the GSM-R) and the 158/9's as said by BestWestern have both CSR & NRN because of the area's they cover. The 455's were originally fitted with DOO equipment, however when they went for refurbishment the DOO equipment was completely removed, the 458's were again originally designed for DOO operations which most of the fleet can still run, only a couple of units have had some of the DOO equipment removed to allow the fitment of GSM-R, the 444/450's were built mainly with DOO in mind but were fitted to allow Full crew working with a Guard mostly because it's part of the franchise to have Guards.
