Pretty much covers it. Also find out if any of them are DCC ready and start with them. It's always good to have something to run while you're converting.

I have a criteria that I go by for installing decoders in older locomotives.
1. Must have nickel silver wheels.2. Must have all wheel electrical pick up and all wheel drive.3. Must not have an open frame motor.4. Must have at least a flywheel on one end of the motor.5. Must be able to isolate the motor electrically from the frame.6. The motor stall current must be 1 Amp or less.7. The locomotive must run smooth on DC.
If even one of these items is not met, I won't do it. Quite a few of the quality locomotives made in the late 1980's will meet my criteria. So each locomotive is jugged on a case by case basis.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.
(Modeling Freelance, Eastern US, HO scale, in 1962, with NCE DCC for locomotive control and a stand alone LocoNet for block detection and signals.) http://waynes-trains.com/ at home, and N scale at the Club.
I've installed at least 50 decoders into older Athearn Blue Box, Spectrum, Rivarossi, and IHC locomotives. The main concern with these older models is knowing whether you need to remove the motor so you can isolate the brushes from touching the frame.
The decoders I usually use for these models are the TCS T-1 or NCE D13SRJ.
Something else I always do is replace Athearn's 'fire in the cab' headlight with an LED.
What are the limitations for installing dcc decoders in older model loco's?
I have a number of Athearn Blue box locos and Spectrum locos that i would hate to eliminate from the roster on my future dcc layout.
Are there decoders available for these older loco's?
As always, all tips and advice are greatly appreciated.
