Proto 2 vs Proto 3

What type of product are you referring to? In a locomotive, Proto 3 does not require a battery whereas Proto 2 does. In my opinion, it's best not to ever have to bother with replacing a battery. So I would recommend Proto 3. You could accomplish the same thing by installing a BCR in a Proto 2 setup - but why do it that way unless cost is a significant issue?

There are two versions of Proto 2. From what I have heard, the earlier version is more prone to breaking down than the later version.

Hi Peter,

As Melgar and other have stated, go with Proto 3 if, and when possible. UNLESS, you favorite engine isn;t available with proto 3, then buy the proto 2.

the ps 2  5 volt boards fail quite frequently but also some of there boards last a long time? ps2 3 volt were good boards and usually only suffer a amp ic when you get track shorts, but shorts can kill  any boards including ps 3. ps2 3 volt boards can generally be repaired, ps2 5 volt boards can not be repaired and ps3 board sometimes can be repaired! the difference between ps2 3 volt n ps 3 boards is ps2 3 volt boards can take a 2 meg sound file and ps 3 boards I believe can take up to  a 4 meg sound file.

Only some PS/2 3V boards will take the 2 meg files, there are also 1 meg 3V boards.

yes John but the ps2 3 volt boards  ready to run  sets only used the 1 meg memory file!

Alan, we're not necessarily talking about "ready to run", you're the first guy that's mentioned that.

PS-3 replaced obsolete tech in PS-2.  Just like PS-2 3V replaced the very early and first PS-2 5V boards.

Basically PS-3 gives more memory for sound files, more features, LED lights versus Bulbs, No battery, DCS and DCC capability, Ability to detect DCS on any rail when 2R-3R engine, and some other stuff on the tech side.

It is the last from MTH and what is supported the easiest.  G
