Nice thing about MTF

You have come to the right place. I suggest viewing the S scale Forum, There is plenty of information and pictures. Don't think your engine is unique either. There are many common features between engines. The reverse unit and smoke unit being two. These guys are good and this is where I go when I get stumped.

I do not remove this piece. The motor is made to slide into it and then you screw down the front. I have seen this piece riveted to some cast shells. Removal is more complicated with the smoke unit. The screw must come out that holds them together . Then the motor will slide out.

If you're saying the screws that hold the smoke unit in place must come out first, that's not entirely correct. Before dis-assembly, the very first thing you should do is to remove the plastic or metal smoke tube inside the smoke stack. If you don't do this, you will break the red plastic smoke tube, and it will be very difficult if not impossible to remove the chassis from a engine with a brass smoke tube.

There should be enough tutorials on the s scale threads to completely rebuild your engine and tender. At last count I think I have 6 312's.

Been away and busy assessing everything I have. i want to thank you all for the time to provide this info.

I am waiting on parts from port line and going through boxes. I appear to have 3 nearly complete sets that I want to recondition mechanically, with only minor cosmetics refurbishment.

From what I can tell I have the All-Aboard Pioneer 600 and it is nearly complete with original transformer and I just received a used working 21165 locomotive (mine was not worth fixing). I believe I have nearly all the trees and fences, etc.

I also have what appears to be the Santa Fe Chief Freight form 1957 (possibly cat # 20380). It appears mostly complete with a working coal dump car (original coal!) and working 977 caboose w/ bay window and brakeman. Unfortunately the A-B-A units are in a bad state. I tried fixing them when I was about 10 years old and only made things worse. But, I believe they are salvageable. I am assessing what I need to order to begin their mechanical restoration. I will probably place my next order from port line in the next few days. the A-B-A need some wiring work and complete mechanical rebuild, mostly the engine and dummy engine.

And then the 1947/1948 312 set which is a bit more difficult to classify as a catalogue set. It has no #627 Girder Car for one thing. Otherwise, it has all the earmarks of a 1947-1949 Pennsylvania K-5 w/ automatic log loader set. But may have been a mashup of sorts. It has with it a #636 Crane Car and a #716 Operating Side Dump Hopper Car. Assumed to have been bought seperately. Along with it came the 1948 Atlantic Green #650(2) & 651 Passenger/Baggage Cars. This was a late 60's garage sale find. $10 for everything, if I recall correctly. the transformer is long gone.

Meanwhile I have tested all engines, solenoids and motors and except for locomotive engine rebuilds, everything seems to be in good order. I am compiling a complete order list to bring everything back to a functional state. Not too worried about cosmetics. I think I prefer the original patina, plus a light cleanup.

Questions:

What do you folks recommend for a transformer for the latter two sets? I have been looking at a MRC AC100. Any good?

It appears that Gilbert reproduced the 6-48147 S Scale Santa Fe PA AA Diesel Locomotive Set (484 engine and dummy). Might be a cost effective alternative if my vintage set is beyond repair. I am assuming these are made with can motors. I have not been able to find much on this. Are these any good? Comments on their design?

LOL - Depending on how this goes I may buy another 312 in better cosmetic condition for a rebuild.

Can you tell me if the slotted smokestack that goes into the smoke chamber simply unscrews to allow the chamber to be removed from the shell?
mine seemed tight and I did not want to break it.

The slotted smoke tube will simply unscrew. It should be a brass one.. When smoke fluid gets dry, it can act like glue, believe me!. If it's a red, plastic tube, it probably has been changed. Both are readily available from various parts dealers. And speaking of parts dealers, don't forget Jeff Kane at The Train Tender. He also has tons of parts, will talk to you on the phone for an hour if needed/wanted, his prices are better, and you can save even more buy buying some items in bulk..As far as the Santa Fe engines, they should be ok. I passed on a brand new set, in the box and never run, for $300 bucks. I wanted the passenger color scheme. The Flyonel PA's built back in the 80's or so were junk, and I would stay away from them.. Ask MOPAC!!.. If you need any help. post it here, or PM me..

Thanks for the train tender referral! Good to know there are still guys out there you can call and discuss an order, etc.

Some thoughts on your train collection. The yellow/blue diesels are very desirable, worth getting in operating order. If they were run frequently the power trucks may need a bushing replacement to get the engine working properly.
The 1947, 48 and 49 production items can be identified by year if the original couplers are present. 1947 couplers have a thick shank but no weight. In 1948 a brass weight was added to the couplers. In 1949 and beyond the weight was black. A 1947 312 would have the smoke in tender. 1948 and beyond were smoke in boiler.
Does the 716 dump car have an outside sliding pickup shoe or pickup contacts under the truck between the wheels. The latter would be 1947, the former 1948 and later.
Most 1947 girder cars had a plastic base, either gray or off white. 1948 and later were diecast. Once you know the year of the set you can look for the correct 627.
I am not familiar with the MRC AC100. Since it has horn and whistle buttons it may not be a pure sine wave output. Those buttons will not activate original Gilbert horns/whistles and the harmonics in a non sinusoidal output will cause the horn in your Santa Fe diesel to sound continuously.
