Notes

This page is not yet complete. Some stuff on this page is indefinite and will be cleared up "soon". Some (fairly minor) stuff may still be incorrect. This will be cleaned up, to the extent possible, over time.

The track layout, switch frog numbers, and interlocking names, where given, are correct. Milepost numbers are largely if not entirely correct. The general signal arrangement is correct: i.e., mast vs. bridge, number of heads, number of lamps on each head. On signal heads containing only 2 lamps, the color (yellow/red vs. green/red) is uncertain in most cases. I don't know which colors on which heads are equipped for flashing. I don't know which signals are fleetable. If anyone has this information, please email me. All high signals are approach lighted.

The main tracks have been drawn thicker for clarity; this is generally not done on railroad blueprints unless there is a large number of subsidiary tracks (e.g. near/through a yard). Road crossing mileposts are taken from milepost numbers of a phone cable buried alongside the right of way. Mileposts of railroad structures (typically given to the hundredths of a mile) are taken from the notation on the structure itself.
