Bowser's second RS-3 run will be coming up soon. There's several PRR later styles being offered. The price difference (Tony's as an example) for DCC and sound is $80.

I'm holding out for Nickel Plate and Erie-Lackawanna myself. For $80 I'll let the factory install my decoder and speaker.
Good Luck, Ed

Myself like many of our fellow modelers have no problem installing a decoder. I'm trying to standardize on one manufacturer and Bowser using the ESU decoders is a plus. I'm waiting for an ESU decoder right now that has been backordered for a couple weeks now. I could get the more expensive multi protocol 21 pin for another $20. But I don't see myself ever using other than DCC. I'll save the money and wait.
There are other things to consider. Speaker. The factory speaker and housing is $32 according to the Bowser website. I buy Sugar cubes with housings on Ebay for $10 and free shipping. Also there is a risk of damaging some detail part. While rare, it does happen. Just yesterday I broke 2 truck chains on a P2K 0-6-0 that I am trying to repair the drawbar connector where last week the pin for the drawbar came off with the screw. I'm getting too old for more drama.
I'm a simple man that doesn't ask for much. Something as simple as having the large kitchen trash bags actually fitting the large kitchen trash can would be a start.

wrench567 John. You are correct. The decoder itself will have very little if any soldering pads. For your application all the soldering will be on the motherboard/ light board. I'm not sure if the locomotive will have LED lights. Something else to consider. I've been waiting for the DCC version with train phone for awhile. I missed the preorder and will have to wait for another run. This would be my only RS unit with the above hood number boards and train phone. It would be nice for people running commuter operations if they produce a hammer head RS3 with steam generator. I would preorder that. Pete.

I saw in November that both DC and DCC versions would be available in mid-December but then forgot about it until reminded by a recent thread and now all I can find available is the DC version. I think by buying the DC version through Trainworld and a separate decoder I'll actually save about $30 over what I would have paid for the DCC version.
Thanks for all the replies. I'm trying to process all of this information. I already have more locos than I really need so I don't anticipate I will be buying a lot more and I anticipate that future purchases will come with factory decoders and sound. I have a very specific loco in mind which is a Bowser Pennsy RS-3 which is DCC ready with a 21 pin plug. I was going to buy the DCC version but I missed when it became available and it apparently sold out fairly quickly leaving only the analog version as an option for the Pennsy.
If I am understanding all the comments collectively, there will be no soldering to the decoder itself. That gives me more confidence. To add a speaker, I would solder to the light board, not the decoder itself. If I have misunderstood this, I'm sure someone will correct me.
gmpullman Pete mentioned Nicks Trains and I believe his suggestion needs further notice and clarification. I've installed a few 21 pin decoders using the Decoder Buddy. They were made for eachother. He offers several types and I generally go for the smaller one which allows more room for speakers and wiring. https://nicknixtrainz.com/ I bought mine from Yankee Dabbler and when one arrived with cruncherd pins they immediately sent me a replacement at no charge. Do more research on the Decoder Buddy and you will get some ideas for their use. Last I heard there is presently a shortage of 21 pin decoders. Some of my other 21 pin installs were using the TCS WOWsound decoders and their mating motherboards. Similar to the Decoder Buddy but with stay-alive built in. https://tcsdcc.com/wowdiesel/motherboards Next18, Next18-S and PluX are coming down the path. https://dccwiki.com/Locomotive_Interface Good Luck, Ed

I agree with Ed, get yourself a Decoder Buddy. It has the header on it that a 21 pin decoder mates with. Just wire in the board, install the decoder and you are done.
One caveat: The NMRA only adopted the NEM pinouts for the 21MTC decoder interface in Dcecember 2020. If you already have a decoder, you must verify if it follows the NEM or NMRA pinout. Some manufacturers followed the NMRA standard (at the time), the Europeans followed NEM. ESU follows the NEM pinout because, well, they developed the interface.
This situation should sort itself out in time as older NMRA decoders are replaced by the manufacturers with NMRA/NEM compliant ones.
I have a couple of Bowser C430s that came dcc-ready with a 21-pin connection.
The connection isn't "a plug" (female) -- rather, its 21 pins sticking straight up from the light board.
I used an ESU 53614 on these, they both run beautifully with it. This is a "motor-only", non-sound decoder, however.
The decoder just "pushes down onto" the pins. You want to be careful that they're all lined up properly before you apply pressure!

Soundtraxx also has a 21pin mother board. For hardwiring, they have installed a 9 pin plug. so you can get a standard 9 pin harness to hard wire in. then, just plug into the mother board. this mother board has speaker pads. it also has a set of pads specifically for keep alives. it has extra pads for the other features the 21 pin can do. the decoader just plugs in. the mother board has uneven pin rows so the decoder fits only one way.
I am now working on that very install in an old p2k sw9. I will take a pic tomorrow when I get home

wrench567 I'm not sure if the analog version of the 21 pin mother board in the locomotive has soldering pads for the speaker. Nicks trains makes mother boards for the 21 pin decoders with resistors already installed on the lighting functions and sizable soldering pads. Pete. Yes they have dedicaded pads for speakers.

There are soldering pads on ESU 21 pin decoders, at least some of them, for aux lighting. Mike has it right, speakers are powered via the 21 pin system.

I don't think there are any 21 pin decoders where you can solder anything to it. If you install a sound decoder, the connection for the speaker(s) will be on the lightboard where you plug in the decoder, not on the decoder itself. Many manufacturers use some sort of two-pin connector for plugging in a speaker. You may want to go to Bowser's website to check it out, it might be easier to purchase a speaker from them that is made to plug into their board.
TrainWorld has a pretty good price on a 21-pin decoder that should work, it has both EMD and Alco sounds. I have an engine with one in it and I like it.

Looking at the Bowser website they have some info for adding DCC. It appears there is a JST plug for a speaker on the latest board. If all else fails a decoder buddy mini will have all the connections necessary. Two pin JST connectors with wires are available in multitude of vendors.
21 pin decorders need to plug into something usually a motherboard. You need to make sure you get a NEM 21 pin decorder as Bowser advises or you could end up doing a lot of rewiring. Without looking at a locomotive from the specific production run there is no way to be sure what you have.

The pictures I've seen of these 21 pin decoders look like they don't have any wires attached. If I have to solder a wire to a small connection on the decoder, I'm not going there. There are decoders that have easily accesible tabs to solder to that stick out from the board itself and I can handle those but if the connections are small and/or are within the confines of the board, it's not going to happen.
John,
May I suggest an idea? If you have some old electronics with boards (or even old light boards from trains), you could practice your soldering skills. I'm not the best at it, but have been getting better and soldered a few decoders.
I recently discovered there are now 21 pin decoders on the market. Trainworld is selling this analog Pennsy RS-3 with a 21 pin plug.

I think the DCC versions of this loco have sold out. If I buy a 21 pin sound decoder, just what am I getting myself into as far as soldering. If the plug has loose wires to solder to sugar cube speakers, I can handle that but if I have to solder connections directly to the decoder, that's above my skill level. There's an excellent chance I would end up frying the decoder.
