<revremark>Added masts with short block in their name to allow for Approach Medium aspect in advance of Approach for use in areas where there is short braking distance prior to the next signal</revremark>

<revremark>Changed all of the route fields from normal or diverging to either to make the system rely soley on block and turnout speeds for aspect selection. This will bring the system in line with the B&amp;O 2009 system.</revremark>

<comment>Stop and Proceed Medium can be substituted for Stop and Proceed when there is diverging route through an interlocking. To use, create a logix that states when the signal displays stop and proceed and the turnout is lined for the diverging route, set signal to stop and proceed medium.</comment>
