K-Line Plymouth, now with Blunami

Very nice Pete. The prime mover sounds are similar to the Lionel Doodlebug.

I like the gray paint scheme too. It it original or a repaint?

Bob

Bob, K-Line did the paint. It was a set engine. They also did a separate sale NYC in black. Sounds are for a Galloping Goose. The only gasoline engine sounds I could find. They are part of the Baldwin Blunami sounds.

Horn is also from the Goose but I suspect that would be selected by the company that used them.

If you ever do another upgrade, please consider doing a step-by-step how-to-do-it article for the magazine. I imagine a good number of K-Line Plymouth owners would be interested in doing what appears to be a very fine upgrade of this popular little critter.

Allan, I know its not pretty but here is what it looked like for testing before I cleaned it up. I spent a few days just putting components in different locations until I was able to get all to fit in the space space available.

Only the light gray plastic “firewall” had to have to material removed to make room for the speaker.

Speaker, rear light, and markers in cab shell.

Blunami is the thin white object in front of the firewall. DC DC convertor at the top of the firewall with a bridge rectifier, below it is the current keeper in the white cube and a small relay for smoke unit power to the right of the current keeper mostly hidden by the wires.

Speaker is from Lionel, 12v 2.4 amp DC convertor from Pololu. Many sources for Sountraxx Blunamis.

Nice job Pete, love the fact that you got the smoke in there as well!

Did you swap out the markers for LED's or just drive the stock bulbs?

John, I kept the bulbs in the markers but used LED chips in the headlight and rear light. Rear markers tied to the front headlight and vice versa so total amp draw from each circuit is about 60 ma well under the 100 ma max.

I know the mini Commanders/trackmobile boards would have saved some room but not sure there are any Railsounds boards that would fit even if you replaced or removed the smoke unit. Too bad the smaller TMCC boards are NLA.

As for electro couplers I think by eliminating the current keeper relays or circuitry could fit to drive them.

Anyone thinking of adding Command to these has to make a list of preferences as its difficult to have sound, smoke, and working couplers.

I knew a Current Keeper was important as these engines easily stall on larger switches.

Removing the smoke unit allows you to pretty easily fit the standard RS-Lite board and speaker in the cab.  I like the fact that you got all of it in there, including smoke, I couldn't figure how to get the smoke in there too.   However, I do have operation using my preferred command setup, using the Lionel remotes.  That was kinda' important to me.

BTW, how is the range with the Blunami board stuck in the middle?

John, what are using for a speaker? You have much more volume than I do. Mine was louder with a 2” speaker but I lost a lot with the 1” speaker. Volume set at Max on mine both master and crew talk.

As for smoke, even an MTH HO smoke unit would not fit???

Pete

I used a little salvaged laptop speaker I had in my speaker collection.  I've found that the DB rating of speakers varies widely, and sometimes you get surprising volume from small speakers.  This one has a baffle, which also helps a bunch.  It just fit in the cab with the ERR RS-Lite board  I put Mini Commander II under the hood.   With the MC-II under the hood, I couldn't fit the HO smoke unit, it's quite a big bulkier than the tiny Blunami 2200.

Laptop speakers are a good choice for small speakers, they usually have a well engineered baffle and have amazing volume for their size.

I have the black one # 80. Never saw the gray before.....let the hunt begin! Release the hounds!!!!!!

Bob

Gunrunner do you think your SMT version of the electrocoupler board would fit in the Plymouth with smoke and the Blunami.

If you used something like an HO smoke unit, you should be able to fit this .65" x 1.0" board in.  I'd probably lose the connectors and just solder the wires to it to minimize the thickness.  It won't fit if you keep the K-Line smoke unit, that completely fills the front hood.
