MEC Railfans and Modelers,

I am modeling a portion of the MEC Lower Road during the 1950’s-60’s. I have questions about the aspects, names, and indications for manual switch stands along that line and within Waterville Yard.
The switch stand signals I have seen present a large green circle aspect. When the points are changes the aspect changes to an arrow (red on the Hallowell siding turnout, or yellow on the internal Waterville Yard turnouts).
Q-1: What is the name for each of the three separate aspects I have mentioned?
Q-2: What is the indication for the different aspects?
Q-3: What is the significance, if any, of the direction that the arrow points?

Thank you for your help.

The green target means the switch is lined for the normal route. The red or yellow arrow means the switch is reversed, or lined for the diverging route. What the "normal" position of a switch is would be listed in the Timetable, if it is a main line switch.

Mick,
Thanks for the valuable info. One other thing--is the direction of the arrow (the diverging signal) significant? Does it matter which direction it points?

The arrow points toward the diverging route. If you can find a late 1940s American Flyer tinplate catalog, you'll find a model of this switchstand as part of their S-gauge track switches.

Traditionally, Red/Green targets were used on main line switches, and Yellow/Green were used on
switches not connected directly to a main line (aka inside switches).
