I have a new train for my z gauge a small steam tender
I have cleaned all track using track cleaner and checked voltage all over
the train just will not run
it tries too a little movement then nothing
I tried taking first cog out by motor and runs perfect but no grip and obviously not driving other wheels
put cog in and check all ok and nothing again
please any ideas need some advice

Adrianti,
Welcome to the forum.
You haven't given us many details to make suggestions to. First may we assume that this is a Marklin locomotive? Is it a new from the manufacturer locomotive or was it bought second-hand? Does that light come on?
A couple of guesses at this point assuming a second-hand Marklin steam locomotive. Possibly something called harden oil syndrome (HOS). There was a time when Marklin used a lubricating oil that hardened over time. Check the gearing for a wax-like material. The gears may need to be cleaned and re-oiled. The other possibility is that the locomotive has been taken apart and improperly reassembled, with the drive rods positioned wrong.
That is about all I can suggest without knowing more.
Mark

Strange : numbers beginning with 99 are in Germany for narrow gauge steam engines !

I believe the number is 89: This appears to be an older engine so HOS is a possibility. When you disconnected the motor from the cogs, did the wheels also turn freely? A good source of information to get you started is: www.zscale.org/articles/revival.htmlHope this helps, Mark

I saw this engine first when Z-scale appeared, together with some other steam engines with "simplified" articulations. Maybe it's as old as Z itself. On a catalogue from 1973 it was shown on ... a modeller's pipe ! Maybe You have got a real "collector" model ...

It sounds like you have a Marklin 8800 seires 0-6-0 steam loco The 006 road # on the cab indicates its a older but very common Loco it can be found on eBay regularly in the $30 to $50 dollar range. As Mark said the to most common problems with these are, #1 Hardened Oil Syndrome "HOS" and #2 having the wheelsets/drive gears installed incorrectly, which is usually the result of someone trying to fix problem #1.
You said the motor runs so Like Mark I suspect your problem is either HOS or the Wheelsets / drive gears are not installed properly. I recommend you disassemble the bottom end clean, reassemble, and lightly oil. one or 2 drops of Labelle 108 oil is all you need. With Z scale Less Is More. adding too much oil will only cause more problems down the road. Do not over oil
for dis-assembly and re-assembly Search Youtube for "8864 Take-Apart" The Chassis in this video is very similar to your Steamer it will show you how to dis-assemble and re-assemble the drivers and gears.

Is is possible this loco is out of quarter? Yup if removing the side rods fixed the problem, that is Exactly what the problem is/was. Like i said above the wheelsets/drive gears were reinstalled wrong. They need to be re aligned or Re Quartered as it were before it will run with the side rods reinstalled. David

Look at the above image of the 0-6-0. There are no side rods connecting the wheel sets. There is only the drive rod. So the nice thing about servicing these is that the quarter of the wheels doesn’t matter because the wheels sets aren’t linked.

On real steam engines the side rods on the two sides are out of sync by a quarter turn. With the steam chest/engine, there is a power stroke as the drive rod/piston goes in and out of the steam chest, so power strokes are at 180°, two points on the wheels. If the axel, connecting rod, and steam chest are perfectly aligned when stopped, the locomotive would have no torque to be able to start moving the locomotive. So on the opposite side the seam chest is out of sync by a quarter so power is always able to be applied. This also helps with smooth application of power when moving. Here is a link to a video/process for cleaning Marklin locos with HOS. It is in German. The guy is running the engine in an isoparaffin oil available in the EU. But aside from taking off the locomotive shell, he avoids taking apart the locomotive gears wheels. They are a pain to get put back together aligned. At least on the 0-6-0 you don’t have to worry about the connecting rods. But it is still a delicate task because the wheel wipers want to pop up. A lot of patience and fine tip tweezers usually get the job done for me. www.trainboard.com/highball/index.php?threads/cleaning-märklin-locos.122508/
