it looks nice , you have mentioned couplers being at the correct height ,I have come to the stage in my lay out that some couplers are not even close to the other cars they couple up but it could be better ,
how would i adjust them ?Or could some one point me in the correct direction .thanks

The idea is to either shim the coupler or the truck in order to raise/lower the coupler to the correct height. There is an NMRA standard for coupler height, and you can check what they are "supposed" to be by either measuring or using a gauge from the NMRA or Kadee. Or, you can find the height the majority of your couplers are at, and adjust the others to match the majority. My HOn3 couplers I just compare to the tender of a Model Die Casting locomotive.
If your couplers are too high, you can either file some off of the bolster that supports the truck, or make a shim to go between the coupler box and the body of the car. Most cars will not have a separate coupler box, so you would need to trim off the coupler box and use the kadee box shimed to the right height. If you choose to file from the bolster, remove the truck and file from the pivot area where the truck meets the body. Keep in mind that filing from the bolster will reduce the clearance the truck can turn in, and it may cause interference with details.
If your couplers are too low, you can place shims between the trucks and the body. Several companies sell shim washers - Kadee and Walthers come to mind. Adjusting the coupler box for too-low couplers is difficult, so shimming the trucks is the best option.
One more option is to use the overset and underset shank couplers. I know Kadee makes them for HO, but am not sure if the others do. If the coupler is too low, swap it for an underset shank coupler and see if it solves the problem (it usually will). If the coupler is too high, use the coupler with the overhead shank.
In standard gauge HO, I try the underset/overset shank couplers first. That is not an option for HOn3, so there I am forced to shim bolsters.
