I tend to think this is user induced to cook a resistor.
Sure "User induced" (even by me by a collision at a switch that connected aux power to track power), but it's still something that needs to be fixed, right?
I've found at least one thread here that addresses this 2 ohm resistor, so I'd like to (constructively) put some input to it:
- 2 Ohms: Decided by Lionel for whatever technical reasons
- "Metal Film": Small wire-wound devices, not unlike the wire you see in any glass-enclosed fuse. The wire acts like a fuse that burns up and opens a shorted connection (protecting expensive electronics).
- "Flame Proof": A composite design of the resistor manufactured to break connection without over-heating or long-term heat generated.
- 1/4 Watt:Calculated by Lionel to burn-up prior to the (expensive) electronics getting destroyed.
I wonder if "Flame Proof" is necessary if the entire connection is encapsulated in heat-shrink tubing (or for that matter, if the original Lionel device is "Flame Proof"). Without color-band markings or such, it's impossible to tell.
For a whopping $6 on eBay I was able to purchase 5 of these resistors and enough heat shrink tubing to fix 4 more in the future.
And that's with shipping included!
