What do I have here???? Info please....

3rd Rail locomotives of that era came with Seuthe (spelled something like that) smoke units and QSI sound systems.  Yes, there should be a 9-volt rechargeable battery in the tender.  The smoke units run on a few drops like 5 or 6 of a lightweight smoke fluid.  Mine had problems with MTH smoke fluid but worked well with LGB fluid.  I never tried Mega Steam in them.

I don't know a thing about the system in that locomotive, but it sure is a honey!

Sounds a lot like QSI's old ProtoSound 1.0 system that Weaver, Williams, MTH and some other companies used in the mid 90's. I had an old MTH PS1 RailKing engine that did the same sound sequence as your engine in question.

dave you shouldve got a hold of me..it got the old QSI in it...Id installed a MTH proto1..way better then the QSI 3 stack board system thats in it..with mth unit you'll have squeeling breaks and station sounds...also installed  mth proto 1 smoke unit in it. that id moditified and it blows out the smoke too....But Im going to upgrade it to tmcc..I have a TAS EOB system that came out of a steamer..going to put lionels S1 sound board in it..

Dave, I cannot add anything to this post to be of help other than to tell you that model

is one fine looking piece of work. Lucky You !!

Thanks guys......good info. I seem to have better luck with older QSI boards than any MTH boards.

Completely obsit with me...I have better luck with the mth proto1..Id have a bunch of QSI sound chips..wanted to try them out on my Q2..well they didnt work or something..try to put the orginal sound chip back in my Q2 QSI and nothing..not very happy about it..so I threw in a MTH proto1 in it..

To change the sound chip on an old QSI board it has to be re-initialized. This requires special equipment that QSI provided to its service facilities. The late Art Boynton re-initialized a couple of them for me. 

man i really hate them//at least mth proto1 you dont have to do that..wonder where i can get it re done at? wondering if qsi can still do them?

ok I did some looking and found out these guy took over the scale tin rail business...going to call them tomarrow..

I hope the new guy puts Art's web site back on line. There was a tremendous amount of information there.
