- store.mrhmag.com - How much side-to-side slop is okay in model railroad trucks? Joe Fugate demonstrates good and not-so-good side-to-side wheelset slop, and along the way illustrates how to test ideal rollability as well. Joe covers this and much, much more in his three book Run like a Dream book series, available for pre-order now. The trackwork book is available now, and pre-order customers get sneak peeks of the other two books as they're being written!

Nice Segment! Thank You Mr. Fugate! MoPac Jack
Thank you excellent information .
Excellent advice. I have long advocated minimal side to side slop. Reboxx wheels with their variable axle lengths are a great innovation. btw - .088 width wheel treads work flawlessly with HO code . 083 Atlas switches.
(Joe Fugate) I agree with beyondDCC, flawlessly is hardly the word for it. Try this -- whenever a car derails (even once) take it off the railroad. I did this and eventually every code 88 wheelset car was no longer on the railroad. Of course there were code 110 cars in the collection as well, but NO code 88 wheelset cars survived. This resulted in me banning code 88 wheels from the layout and going to strictly code 110. If you follow stringent performance standards, you'll find code 88 wheelsets are anything but flawless on track designed for code 110 wheels.
The moment you think you know everything Who Dremt table toys had a universe of physics and art and sciences hidden behind the magic !?
I was running a new Athearn Genesis GP9 without the gear covers ( I was lubing the gears to see if I could cure the loud gear noise [I believe it is the gears]). It had a tendency to derail without the covers in place. With the gear covers back on it runs fine. I did notice the Athearn locomotives I just got have more play in the wheels (as you describe in your video) than my Walthers Proto and Atlas Master Gold locomotives. I am new to the hobby. I would think that the Athearn locomotives should not have so much play. I just ordered your Run Like a Dream book series in downloadable format. A lot of great info, can't wait for the locomotive book. Thank you again.
I have 4 bluebox cars, and it might not always be the truck that's the problem, it had a warped rail that only agreed to cars that are not articulated and C trucks going clockwise. A note for reference I had a bluebox maxi-3.
So yeah, I was testing the wheel spin and checking slop and some improvement would be good. I have a good NMRA HO gauge for testing flanges, track spacing and coupler height and other things. I never changed the wheel sets on those intermodal well cars. How about how much play should the truck swivel have?
those wheel sets will work on different cars. I have a coal car that seems to not like my switches and goes off while the other cars stay on and also both of my intermodal cars seem to go off on 18 radius curves not on all the curves though so they are somewhat proned to the littlest deviation. As my caboose was coming into the switches in the back, it would go off. I weighted that to the NMRA standards, I tried kadee sets. Pretty much of my cars have kadee wheel sets and all have kadee couplers. So I would like to know where to get the good wheel sets in video.
Easy enough but what about the wheel slop on a locomotive?
Wait a minute, you can allways put some kind of spacer to the inside of the truck and have the wheels symetricaly positioned. And with smaller side movement. Right?
@mrnicehearted - Correct. The trick is doing that without destroying the realistic look of the truck and wheels. Better is to replace the truck sideframes with ones that don't have as much slop, though.
Needle point bearings are so small they have a bubble pointed cleaning \cutting tool but little filler shimms sounds to much Just replace side frame \ truck if to much play?
La
what are the best replacement trucks for 1940 era cars..kadee? what number Kadee? Is there some kind of chart for different era trucks?
How can you repair "side to Side" wheel slop? Can you bend the truck in somehow??
My Athearn .bombardier cars are horrible in this respect. Totally non free rolling. Any suggestions ?
First, try replacing the wheelsets with all metal wheels - both metal axles AND metal wheels. Second get and use a Micro-Mark truck reamer. Third, apply powdered graphite lubricant to the axle tips. If all else fails, replace the trucks with something better.
@@MRhobbyist Athearn Bombardier trucks aren't the typical trucks with journals. They have internal bushings and the axle ends are exposed, so the reamer would be of no use. Graphite helps, but the set I bought more than a decade ago have been relegated to a box in storage. I could never get them to run reliably, and it isn't my trackwork because all my other equipment operates almost flawlessly.
What brand of metal wheel sets are those in the video that spin really good?
The trucks shown are: Ring Engineering (perfect minimal slop and superb spinning), Bluebox sideframes with Intermountain metal replacement wheelsets (really bad slop).
Model Railroad Hobbyist magazine thank you for the reply.
based on this video some of my trucks aren't that good but they do not derail...
Trucks aren't sturdy enough. All some sort of plastic then lots of warping.
sweet i must be a god cuz all my wheels have play yet never derail maybe your track work sucks ?!?
I have no doubt some get lucky. But if you want something that works for everyone, lucky or not, eliminating side-to-side slop really helps. I prefer not to rely on luck alone.
its not luck its skill and really the side to side movement isnt a derailing problem slightly bent axle are though
Skill doesn't change the laws of physics.
how wrong you are skill enables you to control physics to a percentage
Fine, then these techniques work for folks who are mere mortals in regards to skill
