Run-in.
Posted by Anonymous on Thursday, September 4, 2003 4:23 PM
What can be done to elimnate car run-in? [8]
On my grades the cars make a thud, when going down grade as each car pass over the sumit point (five cars, five little thuds). Speed has little to do with it, increasing speed to string out the train at model speeds seems to be unrealistic.[:)]

What you have is an example of Newtons Law. It is no different to what happens on a real railroad. I have the same situation on my own model railroad. In fact I enjoy watching a long train of loaded ore cars going down a grade and seeing the couplers alternatively bunch and then string out. It just adds that other small amount of realism to running the train. Sit back and enjoy.

regards, Howard

I really don't know of anything that will stop that, it's just one of those things we train buffs kinda live with. You could add sound to your locomotives and then you won't notice the run in so much.

Micro-Trains makes little springs that slip over the end of the axles and drag against the truck frame for N scale, they might make same for HO if that's what you're using. Or other small coupler springs might work. These increase the friction and are used on the last car. This might prevent your problem, you'll know when you try it.

They do that in real life and since we are modeling a real thing I would say it's a feature, not a defect. I remember when I was real young the older engineeers would still back up and put in the slack like they use to do with steam. Then they would take off forward with a sound of rolling thunder as the slack came back out. They don't do that anymore, but I can still hear it in my mind. That's what you are hearing and it's normal in the real thing and models too.
