Can a too low temperature have a negative effect on Rokuhan turnouts ? Is there any "grease" inside which can "curb" the flipping of the moveable parts ?
Living in snow country, I’ve operated the Rokuhan straight turnouts and crossovers down to about 3-5°C without issues. The ones I’ve opened do not have any apparent lubrication. If you’re using power routing, I’d discourage any lubricant that might cause problems wit electrical contact.
