This has never been dropped and is N scale SD Mac 90 with sound.Always ran till this morning and I get all the sounds and whistles.At first it would move a little and make a rough noise but now it will not budge and all the sounds are there.It baffles me what happened since last night.
What brand is it? Also is it DC or DCC?

It is an atlas and it is DCC with sound.
SD60 maybe? If it really is an Atlas engine (Atlas hasn't made an N scale SD90 MAC); check the connection where the motor contacts touch the two pads on the bottom of the circuit board. Poor motor connection is a known problem with all Atlas N scale engines. Lights will light, sound will sound, but it won't move.

I'll try that and let you all know.
I have new information. It is a Kato and N scale and DCC with sound and has always run vewry good.This morning I start it up and I get a noise that sounds like it's off the track.I took the shell off and I get all the sound and it is NOT off the track and goes around full speed butr has a clunk noise that sounds like it would be off the track but it is not.I see the decoder and everything works except I don't like the terrible sound it makes. It runs down the track like nothing is in the way. What gives?????
Do I split the locmotive apart and remove the decoder to see the gear box?Is this farly simple for a begginer to do?

Hopefully, there is a sheet in the box that shows you how to remove the shell from the frame.

Yep, Kato made an SD90. Its design should give reliable motor contact.
You can loosen the frame screws- one at each end- Only a turn or two. Pull the trucks from the mechanism. Gear box is in each truck assembly. Carefully inspect for any foreign matter up in the gears. I had a Kato truck that made a clicking sound. It had a piece of ballast up in the gear box. If nothing foreign is visible, you'll need to take it apart. You really want to check the sheet that came with the engine before doing so. Look for cracks in the gears after wiping them off with some clean cloth. Use a magnifying glass.
It is over a year old and a friend of mine installed the decoder awhile back.I had no troubles untill this morning and I hear the clunk clunk while it is moving.It has normal speed and the sound still works. I have it striped down to the chassisWhat next with it falling apart???
Don't panic. This is something that you have to deal with when dealing with anything mechanical. Just take your time and refer to the insert that was mentioned above. Also visit any kato forums which should give you some good info.

mfm37,I took it apart and I have a lighted magnifing glass.I took the wheels off and took the top gear out of one of the wheels and saw a couple of small pieces of sand.I picked them out and the other wheels turned freely and I put it back together and it runs great. The only hard part was the brass pieces from wheel to wheel.This thread is now closed and thanks for all of the help.
Happy you found it! A third hand would be nice when working on those trucks
