Title: Blinking bridge affects train smooth run need help!
Post by: racorsr on January 10, 2011, 07:22:28 PM
Just installed the Bachmann blinking bridge but the train does not run smoothly.  It clearly affects the train operation, does anyone has experienced this problem before, any suggestions? Any help will be appreciated.

You may want a second power source to power all of your accessories, instead of using the same power source for both, or just use one more powerful power source.

Hi racorsr,

I owned one of those many years ago.
If memory serves, the blinking light draws power from the track and is not separately powered.
This is why when the light is on the train slows, and when the light blinks off the train accelerates.
I don't recall if the power is fed via contact strips, or wire, from the track to the light (I'm thinking strips).
Turn the bridge over and check this. Also check for a resistor in the circuit. (I don't recall a resistor, but it has been a long while and memory is not what it used to be).

Quick and easy fix, sever the contact strips you only need a break.
Then solder separate wires to each side of said contact strips and run them back to a separate, properly rated, 12vdc power source.

Used basic train set transformers can be bought at train shows for < $10.

Good Luck
