[PRR-talk] Freight "locals" questions

[Ted Andrews]

Listers: 
 
I have 2 questions. First, did the Pennsy use a certain name for their local, divisional trains. I have heard the words: Locals, Turns, and Drills that I have picked of from other railroads (old and new). But id the Pennsy favor one over others?
 
Second, by looking at the MP229's from the 1950's, it could be seen that many divisions/regions were assigned various road power. In Lines West, the typically road power assigned to divisons were GP-7's, FP-7's, and RS-3's. Specifically, the there were Sharks assigned to Crestline enginehouse; in the 1955-1956, Crestline was home to several PA-1's which were assigned to the Fort Wayne Division. Finally, Columbus, Ohio was home to many interesting diesels including C-Liners and Erie Builts. Similar assignments can be noted from all over the PRR system.
 
My question is how were these engines used with respect to the Pennsy system pools in Enola? It is my understanding that the pool of engines, typically the F-7's (and later GP-9's) were assigned to interdivisional and interregional frieght trains. Then how were the engines assigned to the divisions/regions used? Were they used in intra-divisional / intra-regional trains (ie trains the originated and terminated within the same division/region)? Were these engines ever used in the system pool as warrented by traffic demands? 
 
I am attempted to put together a motive power estimate of what type of power ( and frequency of use) that one could see on a specific line. This estimate would not be scientific but just and estimate. Understanding the relationship of the division/region assigned engines with respect to the system pool engines would help preparing this estimate.
 
Thanks in advance for any information or guidance that you can provide me. 
 
I will submit this estimate to the lists for comments, criticisms, questions, etc. Motive power assignments and use are almost as exciting as reefer trains!
