What is the difference between PECO Insulfrog and Electrofrog?
Insulfrog uses a bit of plastic at the frog to stop the rails making contact. Electrog frog has gaps to isolate the frog which then needs to be switched. The insulfrog needs a gap large enough to stop wheels making contact between the two different polarity rails.
What is the difference between a single slip and a double slip?
The difference between the two is rather simple. A Double Slip allows for two possible routes in either direction. A Single Slip offers two possible routes for one track through the crossing. For the other track only one route is possible, with the single slip functioning as a crossover only.
What is a double slip turnout?
Double slip turnouts allow a train approaching on either of two converging routes to select either of two diverging routes. A double crossover allows trains on two parallel tracks to shift to the other track while travelling in either direction.
Are PECO Electrofrog turnouts DCC friendly?
The Peco Electrofrog turnouts are power routing right out of the box and therefore are not DCC Friendly.
How do you make Peco Electrofrog DCC friendly?
PECO Electrofrog – Modifications for DCC
- Cut the wire bonds between the frog and the closure rails.
- Solder some wire bonds between the stock and its related closure rail.
- Using the factory installed wire at the heel of the frog connect a Frog Juicer or a SPDT switch to power the frog.
What is double crossover?
Double crossover may refer to: Two pairs of railway switches forming two connections that cross over between two parallel tracks. An artificial nucleic acid structural motif used in DNA nanotechnology.
What is the difference between turnout and crossover?
Basic types of turnouts include a “Single turnout” that diverges one rail track into two directions, a “Diamond crossing” that intersects two tracks,and a “Crossover” that connects two side-by-side tracks.
Are PECO Insulfrog points DCC friendly?
The PECO Insulfrog is a power routing turnout. The term Power Routing indicates that only the route selected by the switch rails has power. This is accomplished by controlling power to the point rails. Out of the package it is 100% DCC Compatible.
How do you calculate a double crossover?
Expected double crossover frequency equal the product of the two single crossover frequency
- expected double crossover frequency = 0.132 x 0.064 = 0.0084.
- Total double crossovers = 1448 x 0.0084 = 12.
- Observed double crossovers = 8.
- c.o.c = 8/12.
What is single and double crossover?
Single crossing over. Double crossing over. Definition. The crossing occurs at the single point along the entire length of the chromosomes. This double crossing over occurs at the two points in the same chromosomes.
