[CBQ] Double heading

["Rupert & Maureen" <gamlenz@ihug.co.nz>]

If you perceived the difficulties in getting two engines to co-ordinate their 
movements on a train consider the line in New Zealand just north of Wellington 
where the gradient was between 1 in 14 and 1 in 16 and up to five Fell engines 
were used, spread through the train on the upward journey and all of them at 
the front on the way down.  And this was long before radios! 

The Fell system utilised two additional raised rails in the centre of the 
track, and the engines were equipped with horizontal wheels underneath that 
clasped the centre rails to provide additional traction.  Both the engines and 
the special brake vans (waycars) (one per engine) had additional brakes that 
gripped the centre rails.  An engine and a brake van have been preserved in a 
museum at Featherstone.
