Always a possibility, but not usually the culprit especially after making changes to the track such as screwing it down.
If you're concerned about your transformer, just connect to a lighted car like a caboose. Connect the hot to the car's pick-up and the common to a wheel. Throw the throttle and if the bulb lights, your transformer is OK.
