Second Sections or Extra Trains
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.
Burlington Northern Santa Fe
Symbols are a-bbbccc#-%%e:
(#) section ID
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. The last letter code is an internal mechanism used by BNSF and the logic behind its use has no place in FYM. Its meaning varies from train type to train type and can mean anything from an alternate routing to what kind of commodity a particular work train could be carrying. Please use the section # field for extra trains, not this last-letter code.
CN symbols are of the form CN AxxxBC-NN (e.g. M30131-29), where "C" is the section symbol. For second or extra sections replace the 1 with 2, 3, etc.
Primary Symbol: xxx
Second Section: 2-xxx
Third Section, etc - 3-xxx
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
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.

Prepend numbers to the primary symbol
Shortlines and Regionals
For shortlines and regional railroads, choose your own system.
Indiana Harbor Belt 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)
--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)
