Brand new GG-1 threw two traction tires

Could have just been a bad set of tires. If they're not tight enough, it'll throw them off. Of course, the weight of the train has a bit to do with it as well. How many cars are you trying to pull?

Be happy it's just a traction tire.

Could have been that one tire was not installed correct and came off . And the second one might follow shortly thereafter since its doing all the work. You should have spares with your GG1 . Try putting those one and be careful nor to over stretch them. A dental pic can be a helpful tool for this work.

I'm pulling 2 williams express reefers,and an Mth military train consisting of a boxcar and 4 passenger cars, with a k-line Red Cross three car passenger set on the rear.I was running an early issue williams trainmaster on this train, which has no tires, and before adding the three Red Cross cars.It could pull the train, but after the addition of the Red Cross cars, it couldn't .I figured a heavy GG -1 could pull it with ease.It did but then the tires came off.Now I'm back to the Trainmaster again, minus the K-line cars.

I have a Rail King GG1 I bought back in 2011, and it still has its original traction tires. This subject has been discussed at length on this forum, and below are the thoughts of forum members regarding the causes of traction tire failures.

What's the rolling resistance of the whole consist?  Are you sure you don't have one or more cars that are presenting excessive load?  Are there grades involved?

 

I've pulled my 9 car MTH Premier Congressional passenger car set with a Williams scale GG-1 TMCC conversion, and it had no issues at all, including the 3% grade up and down. The consist you're describing shouldn't be an issue for your GG-1.

 

Did you look closely at the thrown tires to see if there was any damage?

 

This gG1 is from which catalog?

Several years ago, when I bought my first traction tire diesel engine, I oiled the trucks, and put it on the track.  A couple of hours later, 2 traction tires came off.  I found that I had put too much oil on the axles, as it had worked its way under the tires.  After that, I cut back on the oil, and haven't had the problem since.

Thanks for all of the suggestions. The engine is fairly old even though new. Maybe the tires are just old an hard. I'll just get a new set and go from there.
Thanks;

My experience is lost tires equal too much weight to pull,,,,,,,,,,,,or old cracked tires,

 

zzzzihave had great success glueing mine on with superglue,,,,,,,,,,,,,most guys say don't do this, but I never use more than one drop and then spin the tire to spread.

 

Normally my GG-1's are stump pullers, when they aren't, they go in for service.
