RS-3 additional weight

RS3's seem to be approximately 240,000 pounds. Scale weight would be 9.84 pounds. I just weighed mine at 8.4 pounds.

So 1.4 pounds additional would take it to scale weight. That's been my limit so far, scale weight.

While the axles are ball bearing, the drive train is not as rugged as the newer Aristo prime mover, and I've had several gearboxes strip a gear or go bad over time.

So,I'd add a pound or a pound and a half. Your grade is too steep to use a single engine with that many cars. You really should double up locos.

Regards, Greg

p.s. my loco is stock with the stock lead weight and stock speaker, and a decoder and a small second speaker in the cab.
 
I forgot about the REALLY old ones Paul!

Good catch, might give a visual on how to tell the difference.

The simple way is if the axle tips go into the sideframes they are pre-ball bearing.

If the ends of the axle are flush with the wheels and have a philips head screw holding the wheel on, they are ball bearing.

I would not add any weight to a non ball bearing.
