Turnout Frog Power
Description:
A turnout (switch) can be the source of various problems
in a model railroad. One problem can be a locomotive
hesitating as it goes through a turnout. This can be
caused by a frog with no power. If you have a turnout(s)
that has the capability to have the frog powered you can
improve locomotive operation. This shows how a Team
Digital Servette can control a turnout
using a servo and route power to the frog.
Operation:
Click on the yellow button to simulate the turnout point
movement by a servo. Notice how the relay routes the
correct rail polarity to the frog. The wiring shown below
is very close to the actual except for Wire 1 and Wire 2.
These wires make have to be reversed at the relay
terminals so that the correct rail polarity gets to the
frog. This will be determined by the way the servo is
mounted and linked to the turnout.
