Signal Sequencing
The close proximity of control points at the Tower 26 interlocking can lead to some up-close and personal views of signal sequences that would normally be miles apart.
Here, an eastbound train has an "Approach Diverging" across the diamonds and then a "Diverging Approach" to cross over from Main 2 to Main 1 at Carr St Jct in the distance. This is on UP's Houston Sub just north of Downtown.
