These simply mark the mileage on a block of track. Can also mark fractions of a mile. Presently, I'm calling a baseplate (2 sections of track) a tenth of a mile.
This is a collection of ideas and plans for trackside structures that you might find along a typical railroad. I'm going to start integrating these into my layouts for added realism and interest and wanted to share the plans with everyone. If you're able to find photos and descriptions of additional structures or equipment, please share. For whatever reason, I've had a hard time finding pictures of trackside equipment that is currently in service along with descriptions of what it does and where it would typically be found. It's harder still to find this info for Norfolk Southern which services Huntsville.
Trains should sound their whistle when passing these posts. They usually signal an approach to a crossing or yard entrance. These are marked with a "W".

These are placed near signals, crossings or in yards and house the electronics necessary to operate nearby equipment.

Due to the risk of fire, batteries are not placed in signal boxes. Rather, standalone battery boxes are placed nearby for backup. Similar looking boxes can be used to house electronics for simple equipment.
