performance of [steam] locomotives


Explanation:
These are steam locomotives used in the past as switchers

851
Italian Ferrovie dello Stato (FS), steam locomotive, 851.057. The locomotives of the group **851** have been a group of **steam locomotives** used as **switchers** until the 1970’s.
These locomotives were built by Adriatic network (RA) which built the service line. In 1905, along with locomotives groups then FS 290, 600 and 870 also former RA, were included among those that the FS reputed worthy of further orders in anticipation of the completion of the project of the new groups fit to cope with the traffic growth following the nationalization.
The advent of the locomotives of the 940 group relegated the 851-series to the role of **shunting locomotives**. With a geographical distribution complementary to that of the group 835 of these "interesting cars" they saw service until the end of the era of steam traction in Italy in the seventies.

prestazione delle locomotive
locomotive (traction) power rating


Explanation:
The first two discussion box entries don't really add anything to the question.

Otherwise, as an ex-train, Routemaster bus and Greenline Coach spotter, methinks this is about locomotive traction power and perfomance measurement.

Example sentence(s):
  • The tonnage rating of a modern locomotive, the maximum train weight it is capable of hauling over a given line without undue risk of stalling, is primarily limited by track adhesion considerations rather than by limitations in the locomotive itself.
  • Locomotives have 6–8 HVAC or HVDC traction motors rated at 500 V DC minimum or 1000 V AC minimum.
