- I'll attempt the second part about why some point one way and some
- the other. Basically, turning around an engine involves a "dead-head"
- move. Although short, it does take crew time and produces no income
- for the railroad. The engines are simply coupled together in the
- orientation that they are found.
-
- When running multiple units, (generally) only the front unit need
- have the cab face the front, mainly for headlight and (here in
- Canada) ditchlight purposes. Although I have seen the odd peddler
- with the front unit actually backwards.
-
- Now for the first question about why differnt types of engines are
- used. Someone else could probably do a more concise job of explaining
- this than me, but I would suggest reading the section called,
- "The Jobs Locomotives Do" in Kalmbach's "The Contemporary Diesel
- Spotter's Guide", pages 315 to 329. (ISBN: 0-89024-088-4)
-
- It gets a little techincal, but does give a good explanation about
- this area.
