As I understood, first letters means area (L, Q), numbers means westbound/northbound (odds) and eastbound/southbound (evens). So what means Q439-02? Q is area (is anywhere available list od areas?), 439 means westbound train - is 439 order or what? Includes this number priority? And what means -02? It's order for this day?
The primary designator for all CSX Merchandise, Automotive or Intermodal trains is the Q - Q439+2 digit date of origin.
A alternative schedule, for say 439, would be designated L439+2 digit date of origin
A Rerouted schedule, for say 439, would be designated R439+2 digit date of origin
A additional section of 439 would be designated S439+2 digit date of origin
Each scheduled train has a scheduled route and scheduled 'work' to perform on that route. 439 is a schedule from Selkirk, NY to Hamlet, NC with a scheduled set off and pick up in Baltimore and a scheduled pick up in Richmond and Collier. If it were to be scheduled to have a Philadelphia set off and pick up one day a week - it would operate as L439 on that day. If the train were to be operated from Selkirk to Buffalo to Cleveland to New Castle to Cumberland to Richmond and then on to Hamlet - it would be operated as R439 for the time during which the train is to be operated on this reroute.
CSX has territories that operate as East-West and other territories that operate as North-South. As a practical matter - former Chessie & ConRail territories are East-West; Former Seaboard territories are North-South. The even-odd train numbering can get turned around when you have a train that goes from North-South to East-West - to wit. Q401 & Q415 originate at Cumberland and operate East until they get on the RF&P Sub at Anacostia, DC where they become Southbound trains for the balance of their trips to Richmond and beyond. Their counter points Q400 & Q416 originate at Rocky Mount and operate North to Anacostia where they become Westbounds to Cumberland.
As a general matter:
Q (L, R or S) 001 to 199 are Intermodal trains
Q (L, R or S) 200 to 299 are Automotive trains (auto racks or auto parts - loads & empties)
Q (L, R or S) 300 to 399 are Merchandise trains operating E-W on the Eastern part of the System
Q (L, R or S) 400 to 499 are Merchandise trains operating N-S on the Eastern part of the System
Q (L, R or S) 500 to 599 are Merchandise trains operating E-W on the Western part of the System
Q (L, R or S) 600 to 699 are Merchandise trains operating N-S on the Western part of the System
Q (L, R or S) 700 to 799 special commodity trains operating all over the system (Juice Train is Q740 for example)
N T U & V are the prefix for various characteristics of Coal Trains
G is the prefix for Grain trains - both loads & empties
K is the prefix for Bulk Commodity trains other than Coal & Grain - both loads & empties
E is the prefix for empty hopper trains system wide (note some empty hopper trains operate round trip under their loaded N T U & V train designations)
Divisional local freights & road switchers use
A B C D F H J M O as there prefix with the regular assignments being in the 700-899 range; extra assignment in the 900-999 range.
Regular and extra passenger movements have the P prefix.
Special trains of many varieties are given a W prefix
Extra trains have the X prefix.
Foreign Line trackage rights trains are operated with a Z prefix
Hope this sheds a little light on what, to a outsider, appears to be the madness of the CSX Train Naming nomenclature
