Reply to "TIU MODIFICATION - SERVICE BULLETIN"

I had the service bulletin preformed on my revision L TIU during warranty. The tiny TVS diodes were replaced with the larger ones per the service bulletin by MTH. 10 months later and so far so good. The worst derailments I've had have been a car wheel coming off the track through a switch and touching the center and outside rails, so nothing crazy.
