Welcome!

This blog details the development and construction of my newest model railway. The biggest challenge I've set myself this time is the balancing act I need to pull off between my hobby and my MOW Crew Chief, Mr. Circus Peanut. I can't simply fire him (he's got a good union).

Managing Couplers

Since one of my goals is to eek out some level of Operation (with a capital "O") on the new pike, I've come up with a solution to hands-near uncoupling for any spot I need to set out a car... The Knuckle Buster™ Manual Uncoupling Tool.

           
 
This is a disposable ball point pen with a nail inserted into the ink tube. A tiny neodymium magnet is stuck to that and a short piece of the barrel is cut off and placed over it. This way the magnet can retract into the tube without trying to bring the coupler with it. The tool is placed in contact with the top of the knuckle. The magnet is lowered, making contact with the metal blade that protrudes from the top of the coupler, and lifts it up. This unlocks the knuckle. After which, the magnet retracts inside the tube. It's like I told my wife, "I got brains I ain't even used yet!".
