The South Jackson yardmaster's other hat tonight is Toh Junction tower operator. After the eastward train made it to Browning and cleared the Toh Jct. interlocking, he set the turnouts to give us a green signal to proceed eastward from South Jackson to Pocatello in main staging.

If you look very carefully, you can see the green indication on the search light signal just before the mainline punches through the sky.

There are three tracks going through the sky here. From right to left they are:

• Spur leading inside the Deschutes printing building (cardboard mockup)
• The South Jackson drill track
• The mainline between South Jackson and Toh Junction

Just in front of Scott's left hand is the control panel he uses to operate Toh Junction's turnouts.
