I haven't gotten the slightest idea where or what it was from but about a month ago, I spotted an ASC unit just sitting outside the shop.
Right now they might be focusing on the 105 to be repaired since it was actually inside the shop with the 151 (although the 151 was probably in there for minor ajustments). People never thought the 261 would breathe anytime soon yet 5 months later it's back on the main.
If I remember correctly, wasn't 156 the best pulling engine according to some NYA crew?
