Thank you Phil.  This brings another question to my post steam (& waycar) life. 
 How did they keep the speeds of both the diesel and steam locomotives close?  
I assume just good ole' experience?  Or was there a trick or signals?  Thanks 
again.  This is great learning material.

Hello, Ralph - During the 'transition' period it was not uncommon to see steam 
and diesel locomotives working together, although the practice was rare on the 
Burlington.  Flatland railroads would often doublehead to move locomotives to 
another terminal without incurring an additional train movement. (A light 
engine on the mainline is a 'train').  Mountain railroads would often have 
steam locomotives in 'helper' service, and they would tie on to whatever power 
was assigned to a train - steam or diesel.  And, yes, multiple engine crews 
were needed.  Each engineer handled the throttle on his own locomotive, but the 
engineer on the lead locomotive took control of the air brakes on the train.  
That was the only 'MU' (multiple unit) function that existed when steam and 
diesel were worked together.  Diesels just didn't know how to "talk" to a steam 
locomotive!  Only a few steam locomotives ever learned to talk to a diesel - 
the Mid-Contin ent Railway Museum's C&NW 4-6-0 #1385 was fitted with a 
rudimentary diesel control setup to handle the more modern locomotives that 
were 'assisting' it.  But the engineer was handling the diesel throttle 
separately from the steam throttle.  The tender had an MU receptacle for the 27 
point jumper cable!  Phil Weibler 
  

  I have been browsing at the photographs posted at CastleGraphic.com.  Under 
the 01 AUG 05 collection are many photos of the 4000 series Hudsons.  Towards 
the bottom one of the photographs titled "4003 January 1953" depicts lead 
locomotive 4003 followed by a GP7 or 9.  I can't recall seeing consist with a 
mix of steam and diesel power.  Did this happen often?  When it did, were two 
engineers required?
