Ok Mookie,
Get out the ZTS book I gave you and find the page with North Yard on it.
If you’re looking at the page in the same manner you would read a book, then north is up.
A lot depends on how any railroad orients its self, either east/west or north/south.
PTRA is a north/south road…North Yard is our main terminus, so anything headed to north yard is traveling railroad north, away from north yard is going railroad south.
Our tracks are numbered so that if you face railroad north, the track numbers start on the left, and get progressively higher towards your right.
In north yard, that means if your facing railroad north, track 1 is all the way to your left, track 62 is all the way right.
From any point on our road, if you’re headed toward north yard or facing railroad north, lower track numbers are on your left, higher track numbers on your right.
And as Mudchicken pointed out, we have various “names” for some portions of the railroad and some tracks…we have Santa Anna siding, King’s Pass, Pasadena Runaround, the Katy Neck, the Scenic Route, the Apron, the Butter Track, the Glass track…The Hole, the list goes on, but if you study your ZTS book, you will see they all have numbers, and are divided into zones for timetable purposes.
Most have the tracks name, if it has one, included along with the track number.
Most railroads follow some sort of similar concept, with the railroad compass being the determining factor.
The only way to determine what the number for your tracks at your “spot” is to listen to the radio and hear which track the yardmaster tells a train to enter, then compare that to the train entering the yard, write it down, and keep listening and comparing till you get a few tracks identified…then simply figure out which way the number are going, higher or lower, from your location.
Or you could flirt with one of the BN conductors and con him out of a ZTS book…
