Tutorial 1 - 2 Track Marks


In this model there is one yard with a group of three sidings. The sidings are defined by naming track marks in a special format. Shedmaster rule examimes all the trackmarks, looking for an asterisk (*) which identifies a siding that it can use.

The first part of the trackmark name is any text documenting the usage of the siding. Following that is the * identifier. Leave a space between the name and the asterisk.

After the asterisk comes the Group number (up to 99) and then the Siding number (up to 99). These two numbers are separated by a hyphen or dash (-).

The last component of the trackmark name is a capital letter A or B. When a siding has access from either end then the active storage area is between two trackmarks which have an identical name. One of the names must end in A and the other in B. If there is only one trackmark the it must end in A

Examples of track mark names:

Coal Receiving *15-1A
Coal_Dispatch *10-5A
Diesel_Empty *8-1A
General Use *2-1A

There is another component number that can be placed before the asterisk but in this tutorial we won't be using these.

Shedmaster only uses group numbers and siding numbers so the text part of a siding name is not considered when allocating sidings.


Because we are using a dead end sidings we only need to put one track marker at the beginning of each siding. The track marker must be pointing into the siding.

Track Markers

At the closed end we have the buffers, the name for the buffers must start with the word Signal. They could be named Signal 1-1, Signal 1-2 and Signal 1-3, to match up the siding numbers but this is optional. These buffers take the place of the B-end siding end trackmarks which could be placed if the sidings can be accessed from both ends. Another option is to place special Siding-end markers to indicate the end of the siding. We won't worry about those yet.

End Markers

That's the wagon sidings dealt with, now onto the engine sidings, called MPD's (for Motive Power Depot). Like the wagon sidings, Shedmaster needs to know where they are, so again we use track markers to identify them. The naming convention for MPD's is MPD followed by any identifying name and ending with a letter, A or B. The letter tells shedmaster which end of the siding to use when searching for an engine,

Example: MPD 1A MPD 1B Apart from the letters, the names must be identical. The track markers should be pointing towards each other, into the sidings.


Now we need to set up a couple of track marks for engine movements and token sharing. First off, we will add a token track mark, the name of token track marks must start with a #. We will call ours #Coal Token, and we will place it here. (The example session is different)


Next we want a track mark to help our engine navigate back to its MPD, and also somewhere to stop, so it can reverse the wagons back into the sidings.

engine reverse

OK, that's the markers set up, just add an Engine, and some coal wagons (loaded) to the sidings. Leave one siding empty, as Shedmaster will need to see that there is space for when the wagons are returned. If there isn't space for the wagons to come back to, then Shedmaster will not send any wagons to the industry.
