Thinking about buying a MTH protosound 2.0 diesel locomotive can this be upgraded to TMCC or legacy

Putting a PS3/2V stacker board in would be easier. Plugs on the wiring harnesses would match. Speaker would need to be changed to a 4 ohm.  Just need to know if the engine has 5v or 3v boards. MTH can program the soundset into the new boards too.

It would be a ground up retrofit to switch to TMCC/ Legacy as far as I know.

I'm not an expert, only getting my feet wet with this stuff.

The basic pieces you need for the TMCC upgrade are the ERR Cruise Commander and the ERR RailSounds Commander.  At MSRP, those two kits are $290.

Add to that if this is a steam engine and you want synchronized puffing smoke you have to add more circuitry. If you have to have someone else do the work the bill could easily be well over 500 bucks.

If there is already a TMCC or Legacy version of your engine you are probably better off selling your MTH engine and looking for an alternative.

Wow did not expect it to cost that much. I agree with Norton. Thankfully the locomotive is not mine it is up for bid at Stout auction.  The only tmcc option that exists now is an Atlas version and I doubt if Lionel will make it because the locomotive is an Alco 628 which I don’t think Lionel has ever done

Any complete upgrade is going to be expensive. Obviously a diesel can be cheaper than a steam, unless you want the diesel to smoke as well. Then you’re right back up there again……question is, if you can get the engine at a good price point to warrant the upgrades in your own mind…….If the Atlas version is rare to see on the market, or sky high if it does show up on market, then swapping a MTH model could be an option…if you can accomplish the upgrade yourself, then you can certainly save quite a bit at least on the labor side…..

I do battery conversions on my G gauge locomotives and add Airwire motor controllers. Would the upgrade to TMCC be similar

If you can follow basic install instructions, it’s not difficult at all. Getting your feet wet with a diesel is a lot easier than doing a steam engine at first. I don’t know what’s involved lighting an Alco 628, so that might get a little tricky setting up a lighting circuit, but even that isn’t horrible…..

It's too bad the equation for installing ERR components has changed so significantly in the past few years, as the cost of the ERR products has gone up so much. It used to be a lot easier decision to do an ERR conversion. Those days seem to be gone, now that in many cases it's gotten more cost-effective to just sell the engine and buy another already equipped with these features, rather than spend what has become big bucks to do ERR conversions.

Adding the sound really drives up the cost. If that can be bypassed, it seems doing a conversion to add TMCC and cruise may still be worthwhile.

You're certainly right nowadays.  The combined MSRP of the Cruise Commander and Railsounds Commander is $290 + shipping!  Gone are the days of getting both of them for around $200.

Your right John, I remember when I bought these boards from a guy in Connecticut. I think the total was just over hundred bucks. Then again everything was cheaper. My only issue is I took these boards once to a friend who builds electronic boards for specialty devices. He priced everything out , let’s say it was a lot less. But as my Dad would say “ if you want to dance, you got to pay the fiddler”.

How often do we forget, in any manufacturing business it's not only about what the parts cost, there's got to be a (small?) profit in it to cover employee's wages (labor), shipping and handling, taxes, the cost of holding inventory, and the risk that the owner of the business takes on a daily basis, among other things.

@ThatGuy, I think that you might have some experience in this area from what I've read in your earlier posts so I'm not challenging you on your conclusions, because you've made many points that are well taken.

But, do the rest of us expect someone, say a new competitor, to want to take this on, simply cover only their basic (piece part) costs, and then eat the rest?

(Uncontrolled inflation is the real killer here.)

No I think you took my post the wrong way, I was just thinking out loud. Let’s not forget that a 700E was way over a months pay for most people. As always it is economy to scale. Could I produce a cheaper board as a one off yes, but hundreds not a chance and I know it. In the end it is how much you love it or the sentimental value of the piece.I have converted 100s of engines for people and some are worth about 2 bucks, but to see the face of a customer when the train fires up……….makes it priceless. I’m sure Gunrunner has converted a few that really had no book value…….as I always says it’s yours enjoy it.

To better ask this question. Is there a difference in performance between ERR and a legacy power master

There will certainly be a difference in performance, a true TMCC conversion with ERR will undoubtedly yield better running and more features.  You lose electrocouplers, remote control of smoke and lights, crew talk, etc.  Conventional running is not the same as running in command mode.

Yep, plenty of low cost locomotives get converted.  I did several of the Polar Express set locomotives to full TMCC with fan driven smoke.  The conversion was multiples of the price of the locomotives, but that's what the customer wanted.  I've had people bring semi-scale locomotives that can't be worth more than $75 for a full upgrade.

I even did a full TMCC upgrade with sound on a $5 eBay bank.

The rule of thumb for years was manufacturing cost was 25-30% of MSRP, I doubt that's changed over the years.

Yep- Full ERR upgrade with LED lighting. I don't do it for the value, I do it cause its fun and something I have the skills (sort of), to do. And besides, according to my wife I work for free.......

Always wondered where the Wiener Mobile came from John!

I love it…….what a great idea. What was the underpinning you used?
