Data
NOTE 1:
All vehicle and component weights shown are approximate weights.
NOTE 2:
The light locomotive maximum speed is limited to 75
mph and shall not be exceeded.
This is limited in the event that if all 4 safeset devices are lost (which
results in no
rheostatic brake) the locomotive still has adequate braking via the treadbrake.

Note:
If a locomotive is lifted with the bogie(s) fitted, primary
suspension securing bolts
(see picture inset) must be
fitted between the axlebox and bogie frame to
prevent damage
to components
during lifting.
