It is necessary to use a second or extra section symbol on a train. For these cases, edit the symbol (free text) according to the information on this page. The system varies by railroad. In no case should you append a letter to the end of the symbol.

Symbols are a-bbbccc#-%%e:
a-train type
bbb-origin
ccc-destination
(#) section ID
%%-date originated
e-symbol-specific code
Primary Symbol: a-bbbccc1-%%e
Second Section: a-bbbccc2-%%e
Extra Section: a-bbbccc3-%%e
Note that these only apply to manifest trains. Intermodal, vehicle and unit trains not referenced below, while using the same format as manifest trains, do not use the same section numbers. Please refer to the individual TSARs for variations. Locals and yard jobs use a different code entirely as can also be seen in the TSARs.
For some unit trains, BNSF uses a serial number instead of #-%%, starting with 0-01. FYM simulates this by using day-of-year as a default, but you may change it. Increment this serial number by one for each extra train. Manifest train originating at intermediate points are typically section 4, but may also use section 3. The last letter is not a section code.

Please use the section # field for extra trains, not this last-letter code.
Canadian National
CN symbols are of the form CN AxxxBC-NN (e.g. M30131-29), where "C" is the section symbol. For second or extra sections within 8 hours of departure replace the 1 with 2, 3, etc. For other Extra's needed (say one was departed in the AM and one in the PM) then replace the initial letter of the symbol with X. Example M34041-XX would be X34041-XX.
Canadian Pacific
Primary Symbol: xxx
Second Section: 2xxx
Third Section, etc - 3xxx
CSX
Primary Symbol: Qxxx
Second Section: Xxxx
For extra sections of unit trains or yard jobs, select a new job number. Typical choices are to increment the number by one (U243 becomes U244) or substitute 9 for the first digit of the job (Y102 becomes Y902).
Kansas City Southern
Insert a "2" after the main symbol and before the date. For example, second IDAAT is IDAAT2
Norfolk Southern
Primary Symbol - Extra Symbol
0xx - Rxx
1xx - Mxx
2xx - Ixx
3xx - Wxx
4xx - Xxx
5xx - Yxx
6xx - Zxx
7xx - Qxx
8xx - Sxx
9xx - Oxx
For locals, select a new job number. For example, second A31 could be A99.
Union Pacific
Primary Symbol Extra Symbol tssdd tssddX
Add X after the destination symbol.
Shortlines and Regionals
For shortlines and regional railroads, choose your own system.
Suggestions:
--prepend "2-" (like CP)
--prepend "second " (like "second local job")
--insert a 2 at the end of the symbol but before the date (like KCS)
--change the job number (like CSX)
Indiana Harbor Belt
The IHB has a symbol they use for extra sections (they do not run second sections) for road trains only.
Append the alpha part of the symbol with an 'X' (example: BA2 would become BAX2)
