This page contains notes on the terms used in Locopage. The total number of locomotives in the class, and the number currently in service. This is intended to be the length over couplers . The first figure is the starting tractive effort, the second continuous.
Tractive effort is inversely proportional to the speed.
Most preserved locomotives are with museums or preservation groups, while a few are on static display. I have also set up a Preserved Locomotives page listing all preserved locomotives included on Locopage. I would be appreciative of any such information that could be passed on. If there is a big difference, could you please let me know. Again, there can be a gap between when a loco runs its last service, and is officially removed from the register.
