Bachmann 2-6-6-2 New Run Observvations

Now that I have had some time to get rather Aquanted with my 2-6-6-2, some things have become pretty clear to me. Things that can use some improvemnt, and things that could use some tweaking. First off, This was not a "New" model when it came to me, I bought it as a basket case, after it took a dive nose first onto a floor. It was in pretty bad shape, but this forced me to take it appart and examine the beast from all angles.

One of the first things I noticed, witch is no suprize to anyone I am sure, this thing has a S-load of small details, witch was shocking it faired as well as it did from the fall, Although I have since discovered, they are pretty tough.

Once it was running again, I noticed mine has a Lobe to it when it ran at low speeds, tinkering with it for months, I soon found that the rear Motor had a driver our of quater by a miniscule amount, once fixed it is smooth though all range of speeds.

In the prossess of trial and error in elimnating the cause of the lobe, I bound parts up by mistake, creating drag on the mech. I noticed then, when their is a drag, the rear of the front truck picks up off the rails and vise versa for the rear, Getting the locomotive back to it's loose and running state, I continued to watch that front engine, and under extreme loads, like verge of slipping, the front axel on that front motor actually, in a way, bares down on the rails. in reverse, the rear axel of the rear engine does the same. I am planning on adding some kind of traction tire/bullfrog snot sometime, and I think I know where to put it now.

Bachmann's decoders SUCK, Yeah I am still running it for now, it is a working decoder and my train budget is non existent as of now. My biggest gripe is the lack of options, this thing is locked down worse than an Iphone. seems like all the typical adjustments are not accessable, like speed tables. Yeah, I can adjust the start mid and max volts, but the speed tables is what I use to sync it with the other locos I have. Also the thing is HUGE, takes up a good 2/3 of the b-mann long tender, and the wiring colors are not NMRA, although with the internet, it will be easy to figure out what wire goes where on the board. from what I understand this is a Lenz decoder, but I expect better from Lenz.

Tender swapping is a breeze, I wish other manufactures would take notice. It came with a Vandy tender. and because I føøbied it in the Northern Pacific, this wasn't going to work. I ended up trading strait acrost for a USRA long tender, the swap was just a matter of opening the tenders, unplugging, detaching drawbar, and reversing the prossess on the new tender. I love it!w

Overall I like this run, I hope Bachmann keeps putting out good spectrum steam locomotives, I wanna keep expanding my stable!

I know the loco of which you speak, I was tempted to buy it, but I have a trio of H-4s now as well as one H-5, and didnt need one more. My H-4s run well, but also like to try and lift their pilots from the rails under load; I am going to modify them anyway, to get rid of that &%&^$* dummy coupler Bachmann insists on installing on the front of their engines.

Mine all run pretty nicely with no wobbles (but mine didnt hit the floor either!) and they pull well enough; 15-20 cars is easy, and I wont need them to pull more than that on my small layout. They pull noticably better than the H-5, but oddly the H-5 is one of the smoothest runners I own. Need to bullfrog snot it and add some weight to get it into the swing of things, pulling and pushing on the Pine Creek Sub!

Bachmann is doing OK, but after their gorgeous 2-8-0 and heavy 4-8-2, the H-4 should be a much better puller than it is. Im happy i dont need to run 50+ car trains, I would be pretty upset if i did.

Now if we can get them (or anyone) to upsize it a bit into an H-8 (or even better an old H-7!) I would be in Heaven. Glad you like the 2-6-6-2, they are beautiful little engines. I swapped the tender on one of mine for the bigger VC-16 (the Heavy mountain tender) and dont plan to use DCC, so the cruddy decoders dont bother me much.
Just say no to dummy couplers.
