What is the minumuim radius of the proto 2000 2-8-8-2 and what is the smallest radius it looks good on

[jayl1]

According to Walthers, it should run on 18" radius.  Personally I think it would look better on 24" or larger radius.

To look GOOD - at least 30".

It is all a matter of opion. To me it looks good going around 22".

Good Evening All,

        I have learned from experience as well as listening to customers in the local train store that whenever you see an advertised minimum radius,  add anywhere from 2 to 4 inches to that advertised minimum radius.
        A perfect example of that is the new PCM 2-10-0.    Advertised at either 18 or 22r,   forget it.    !8 inch is out of the question,  and even 22r is really tight for that engine.   The problem is how close the tender is coupled to the engine.   On a 22r curve,  the cab and tender deck can make contact.
        As for what looks good?     You already got a good answer.   It is up to you as to what looks good.   For the Proto 2000 Y3,   Gene is right,   30 looks nice.

The 2-10-0 doesn't but yet the 2-10-2 does . A lot depends on wheel spacing diam of the wheels and blind drivers.
