'''Heritage diesel locomotives''' working on the main line are allocated numbers in the 89yyy series. Generally the third digit represents the power classification and the final two digits are the last two digits of the pre-TOPS number, except where duplication occurs(for example D1015 was allocated TOPS number 89416 because 89415 was allocated to 50015/D415 Valiant). TOPS numbers allocated to SVR locomotives include:<ref>[https://www.rcts.org.uk/aboutlocomotives/newstops-class-89/89xxx.htm RCTS TOPS Class 89 listing]</ref>

Generally the third digit represents the power classification and the final two digits are the last two digits of the BR era number, except where duplication occurs. TOPS numbers allocated to SVR [[Steam Locomotives|locos still resident on the SVR ]] include:<ref>[https://www.rcts.org.uk/aboutlocomotives/newstops-class-98/98xxx.htm RCTS TOPS class 98 listing]</ref> *98186: [[686 The Lady Armaghdale]]

For heritage locomotives, the TOPS number was used for reporting purposes and was commonly displayed inside the cab.  '''Heritage carriages''' used on the main line are allocated numbers in the 99yyy series. The SVR's [[The Severn Valley Railway on the main line#SVR Carriages used on the main line | GWR main line set]] were allocated the following TOPS numbers:<ref>Railway Heritage Register Carriage Survey</ref>*99230: [[GWR 5883 Brake Third]]*99231: [[GWR 1116 Full Third]]*99232: [[GWR 1146 Full Third]]*99233: GWR 9631 'Clapham' Buffet Car ([[Carriages formerly resident on the SVR | No longer resident]])*99234: [[GWR 1086 Full Third]]*99235: [[GWR 1087 Full Third]]*99236: [[GWR 7284 Composite]]*99237: [[GWR 9627 Restaurant Third]]*99238: [[GWR 6562 Brake Composite]]*99239: [[GWR Full Third 2119]]*99730: [[GWR 9615 Kitchen Diner First]]

==SVR rolling stock with TOPS classification codes==Note: Most of the GWR / LNER / LMS era rolling stock had been withdrawn by the time TOPS was introduced in the late 1960s and would therefore not have received TOPS classification codes.
