I am currently in the process of installing new unifrog O gauge turnouts, and have replaced all of the previous electrofrog turnouts that despite the correct adjustments being made for DCC use, seemed to cause smaller locomotives to either stop or jerk when passing over the turnout. However, having installed unifrog turnouts all locomotives now run smoothly over them.
I run a DCC layout, and use of droppers has been greatly reduced to each end, eliminating the need for droppers all over the layout. The unifrog turnouts seem to allow the power to flow in all directions even without connecting the frog wire to the frog connector on the Colbalt Point motors, with no stoppages or shorts at the frog. Plastic fish plates have also been eliminated.
Despite the ease of installation, I have experienced a problem with just one turnout, which showed signs of overheating at the frog and melted the surrounding plastic. I have yet to determine the reason for this, as it has been installed in the same manner as all the other turnouts about 18 in total.
Apart from the above gliche I am quite pleased with the performance of the new O Gauge Unifrog turnouts.
