I have an Atlas Alco RSD4/5 (about 10 years old) that has always had a problem with intermittent pickup. I believe the problems has to do with the specific metal these wheels are made of, and am looking for a solution. I'd like to know:
- Has anyone had similar problems with these engines
- Suggestions on solutions
I previously used CTC32 command control and have just switched to DCC. As I want to have sound int his engine, good rail contact is critical.
I'm convinced this is a problem with the wheels, as all other locos on the layout will generally run quite well (especially after layout is treated with Dr. Bonzola's oil, an outstanding locally bottled track cleaner). I can clean the wheels on this loco and a day later it is back to intermittent operation again within a few minutes. I can apply Dr. Bonzola's oil and wait about a 1/2 hour, it will run pretty well. However, by next day it is back to intermittent. (Any other loco treated with this cleaner will operate quite well for several months at least, and applying drop of oil every 10' or so on the layout is normally sufficient to keep everything working well for weeks, except for this Atlas engine).
I suspected insufficient pickup - the RSD4/5 had 6 wheel trucks that only pick up from 4 wheels, so I added pickups on the other wheels. Very little improvement seen as result.
I am convinced that these wheels must be made of an alloy that oxidizes quickly, as the track cleaner obviously takes some time to have an effect (seems to be a chemical de-oxidation process) and the wheels re-oxidize over time.
I'd appreciate anyone telling if they have had similar experience with such engines and what cure (if any) they have found.
Thanks Rick
