I just received my first N gauge starter set. In the box there are extra couplers. They appear to be different then the ones on the cars and locomotive right out of the box. My problem is the cars will not couple with each other or to the locomotive.  Is this normal to have to change the couplers as soon as you get it?  Thanks for the help in adavance.

Can interior lights be added to passenger cars like in the Durango & Silverton set?
