addition to this the battery, under certain 

 conditions, supplies the lighting and control 

 current, also the power for driving the 

 exhauster motors. Normally these supplies 

 are provided by the exciter, but as the latter

 them from the battery whenever the exciter 

 voltage drops below a certain limit. 

 Each motor-coach is 52 feet long and 

 unloaded, it weighs 33 tons. It is provided 

 with a control compartment at each end, 

 and one baggage, one first, and one second 

 class compartment. The coaches are 

 painted in the well-known red uniform of 

 the L.M.S., and the whole train is a very 

 fine example of what may be accomplished 

 in such a conversion as that described.
