I received my first NS Heritage diesel yesterday...the MTH Premier Jersey Central SD70 ACe (photos below). Plenty of fine-scale, add-on details and excellent paint job. I put it on the track last night and it sounds awesome, especially the unique start-up sounds, and the 8 levels of diesel roar. Easily the loudest and clearest-sounding MTH diesel I own.
Only one, minor out-of-the-box issue: one of the fine wire sand pipes had fallen off the rear truck...not bad considering the many small details on this locomotive. A little JB Weld and problem fixed.
I couldn't run it all the way around my very small layout...it was hitting everything in sight trying to negotiate the 0-42 curves!! I knew this would be the case, so back and forth it went on the straight section of track. She will get to fully stretch her legs when I build a bigger layout with wider curves!
