Well, I went to my LHS last evening and I picked up my Micro Trains SW1500. My first impression was that the shells looks really nice. My LHS told me that apparently, the front light is misaligned and needs to be adjusted slightly. When I looked it up online, I found it detailed here on the Micro-Trains site. Anyway, when I took the shell off to adjust the light, I see that the chassis is from the Lifelike SW8 & SW9 locomotive. I am a little disappointed because I was excited to see if Micro Trains would have supplied a new chassis that could be used with future kitbashes. Well, at least I know it will MU with my SW9's.
