Multi lashup question

Hey all, Question that has been bugging me for a while. When we have multiple head end units, why are some tail to tail,  and some nose to tail?
Now in a yard it makes sense to have them tail to tail, as you can be faceing foward on all long turns, but on the main line?
 
Try not to laugh out too loud.
 
Thanks
Adam

Units are MU'd (lashed up) however they happen to be facing at the time they are coupled together. It doesn't matter which direction they are facing, since they run equally well in either direction, and no special set up is needed when units are MU'd. All you need to do is couple them together, connect the air hoses and MU cables, set up the air brakes for either leading or trailing opreation, and position the headlight MUing switches to the proper position. Of course an air brake test must be run to verify that the brakes are functioning properly. Naturally running the lead unit in the forward direction is normal, and desired, but circumstances sometimes dictate otherwise, such as having only one engine and you have to change directions during the trip with no place to turn power, or the same problem with multiple units facing the same direction. If the latter occurs and there is at least one unit in your consist facing the other way it can be switched to the new lead direction.

D.E. , thanks for the response. Didn't think that it just depended on how the unit's were faceing to start with. Too easy.
