Does anybody know where you can get O ga saw mill set for inside of mill. Table, saw, Etc
Thank you

There are many things that can cause the horn not to blow.
First, what transformer are you using? The whistle rectifier disc may need replacing.
Second, what loco are you running? Take off the cab and sequence the loco into neutral, then use the 'E' unit to lock it in neutral. Do you have a fresh battery installed, and are the battery contacts clean and not corroded? With power to the loco, press the whistle button on the transformer. Do you see and hear the horn relay contacts closing? With the power off, take the battery and touch one end of it on the horn itself. Take a piece of wire and touch the other end of the battery to the horn wire where it connects to the relay. It should blow. If not, the horn is faulty.
To extend the wiring from your switches to the controllers, you can either solder extensions on them and wrap the joint with electrical tape, or for a neater job, use crimp connectors.

The horn is on the coal tender behind loco, thanks on the switch wiring
Sounds like you have a steam whistle, not a diesel horn.
The principal of it working is the same. The transformer puts out a DC voltage when the whistle button is pushed. This pulls in the relay contacts in the tender, energizing the whistle motor which runs on AC voltage. The transformer boosts its AC voltage output to compensate for the extra power needed by the whistle motor to keep the train running at normal speed. If the transformer did not do this, the train would slow down.
If the whistle does not blow, take the locomotive off the track. Make sure the rollers and wheels of the tender are clean of all dirt, as well as the track. Use Naphtha if necessary to clean everything. Take the shell off the tender. Replace any old and cracked wiring to the rollers and motor with SuperFlex wire. Apply power to the track and push the whistle button. You should see and hear the whistle relay close, and the whistle motor should run. If the relay does not close, chances are the whistle rectifier in your transformer is bad. If the relay closes but the whistle motor does not run, the motor may need servicing. Unsolder the wires to the brushplate, remove the nuts holding the brushplate in place and remove it. Clean it, the brushes, springs, and the copper commutator segments of the armature with Naphtha. Reassemble, and put a drop of light oil in each bearing on each end of the armature. If the transformer is putting out the proper DC voltage, the whistle should blow when the whistle button is pressed.
What loco and tender are you running, and what transformer do you have? Literature is available online to help you, but this information would be needed to get it to you. Thanks,

Thanks Larry I will try all of above, Thank you Kurt
The transformer you are using probably boosts voltage when whistle is blown. ZWs & others did this because the old whistles were motor powered and caused voltage drop. You never did say what loco and transformer you're using.
If it is in fact one of the old motor-powered whistles, there is also a special relay in the tender, All wires to and from it, from pickup rollers to motor, must be checked---may have broken off. Using fingers, make sure motor can spin. See if relay pulls in when you hit the whistle button.
Lots of great service information here. The whistle uses the same actuating relay as the horn:
