Ever single NECR unit I plan on will have front / rear ditchlight and operating roof strobe. I made a list of all the detail differences as some have black trucks some silver, others have single clasp brakes and some have double. Other things are minor detail differences such as horn location, decals, small paint differences, Etc. Seeing I have access to just about every NECR and CSOR unit I can always see what has to get changed, unless it’s the 3854 which caught on fire on the train I was running and has been scrapped, lol. If you have any questions you can Email me at MGWSY@aol.com.
