Crew symbols (rarely paid attention to) are 7-character codes beginning with the train symbol. The 4th character seems to always be a letter which probably has some geographical significance, and the remaining characters appear to be assigned sequentially within some predefined range to each crew on the train.

Crews deadheading from one terminal to another get symbols with the "train" portion usually in the range 470-489. If you hear such a train symbol on the radio, it's probably actually a crew in a road cab.

Caution on the even/odd rule in Ohio: on the Columbus and Sandusky districts, east is south and west is north. So geographically, even symbols are heading south and odd symbols head north.

All carriers have their own train naming conventions - those conventions revolve around data processing requirements of the original computer systems each of the carriers installed and or the computer system that prevailed when carriers merged. Since each carrier developed their own computer systems, they also developed their own train naming conventions. Each carrier's system makes sense, in the context of that carriers operations and is functionally Greek to others that are not familiar with the rules which make the train naming system.

In the dawn of the computer age, processing power, memory and data storage were all expensive and system designers designed their systems around the 80 characters available in the standard IBM card - how few characters could be applied to each element of significant data and fit all the required data within 80 characters.

While today's computer age is far different than what it was when the systems started, the legacy computer systems are so ingrained into the present day operations of the individual carriers, unless there are more mergers the existing systems will continue in their present data formats for the foreseeable future.

Does anyone/any website have any current NS train symbols around Harrisburg, PA?
Yes! Check out http://www.parailfan.com - lots of good stuff there including a searchable train symbol database. Gives you origin, destination, lines used, days of operation. Seems to be pretty up-to-date.
