Disclaimer: I know most say Tyce = Junk...

with that out of the way...

I have this loco and need some guidance. I would like to oil it but not sure how to take it apart. The train runs fast...pulls 11 cars but surges now and then.

I ran my new cheap [$40] Bachman dcc train on my dc track. it runs smooth and consistent thus its not the track..

ok off to pics...

What you're dealing with there is not a Tyco, but rather an AHM Alco 424.
Tyco did make a similar Alco 430, but the drive is completely different. The good news is that the AHM is easier to service and -despite being only single-truck-powered- is a worthy candidate for upgrading with one of the affordable can motors from ebay that can be had for 3-5 bucks.

I don't think you have to entirely remove the trucks for cleaning and lubing them as the entire bottom of each truck will snap off to reveal the gears and such. If you can't figure it out, let me know and I'll check as I've got one upstairs somewhere.

Good Luck!

interesting, i assumed Tyco but it does not say that anywhere. It does however say Made in Austria under it.. so maybe i have an AHM 424? i just googled Tyco 76 diesel and got to a page that lead me to think it was a tyco...


yes im stuck on how to remove this to get it going. I read that the gears get messed up on them and im wondering if i have that issue too.. so definitely want to open up the drive wheels to look inside.

i figure this is a cheap train to mess with so if i break it, no harm no foul...

I think I saw the loco headligjht flicker...if so, that would indicate poor wheel power
pickup from the track. You might try cleaning the loco wheels.
The easy way to do this is to run the front wheels onto a paper towel
that has a 2 inch spot of alcohol. Run up the speed as you hold the loco with
your hand...the wheels will spin in the alcohol and clean themselves. However,
if the loco has one rail power pickup on one truck and other truck picks up
the opposite rail that won't work and you'll have to 'scrub' each wheel by
hand using alcohol.

Also make sure your track rails are clean.

If that has Made in Austria on the bottom, it was made by Roco as Eilif indicated.
