What's your curve radii?
Do they derail when run together or by themselves, If by themselves then you might want to check your track and make sure the track and wheels are in gauge...

I think that your cars are too long for your radii.

Gene is correct.

Full length passenger car really need something around 28 to 30 inch minimumm radius curves for reliable operation.

But, you might be able to get away with 22" radius curves. Undecided

Provided the train is not too long, and the track is connected properly, you can use 22". I do it all the time, although I want to get 26" so I can run my Walthers Viewliner as well. But space is finite...

Good Morning All,

      There is another issue here.   The author says that the derailments happen,  especially when the cars are pushed.   If the cars have talgo trucks,   trucks with the couplers attached,  then that will be a problem with either long or shorter cars.   The pressure against the coupler is transfered to the trucks and can lead to derailments especially on tighter radii.  If indeed,  you have talgo trucks,  then you would be best served to body mount the couplers.

He doesn't say who made them or when.  I hadn't considered Talgo since they seem to be more and more rare.  Weren't they designed for tight radii?

Do yourself a favour; don't money around with either long cars and short radius.  Use either short cars and tight radii, or use longer radii.  A lot of this  is going to be a compromise, because most of us aren't blessed with the means to acquire a 100-ft barn, complete with heat, running water, and its own potty.

Go first for quality, reliability, and practicality; then go for the superficial stuff.  There are dozens of ways to make a layout appear longer than it really is; don't go tweaking common sense on the nose.  He has big feet!!

The original poster does not say what scale the Amfleet cars are, nor who made them, and if Bachmann, whether they are new or old production (they're different cars). While an 18" radius should be adequate for the old production N scale cars, the new ones supposedly require 19". Remember, this is in N scale.  If the cars are HO, they probably require 36 to 40 inch radius curves.

You can get away with running most HO passenger cars on 26". It won't look good, but it will work. 30" or higher is a better choice for HO.

If you have long cars with talgo trucks and some that have body mounted trucks, lookout.  They will derail on large curves.  I don't think you have the problem with short cards.  I think the only cars I have on the layout with talgo trucks is one passenger train.

Gene,

       In answer to your question,  yes,  Talgo trucks were designed for use on tight radii.   That does not change the dynamic that when pushing any car,  regardles off length,  the talgo truck may derail due to the pressure from the coupler.   I cannot tell you how many times - as a youngster - I relaid track thinking my derailment problems were doe to poor track work when in reality,  the problem was the talgo trucks on my AHM cars.
