When at York, I will be on lookout for MTH N&W J engine proto 3. Found 5 choices: 30-1633/4-1 (released 2014), 30-1674/5/6-1 (released 2016). Cab numbers aren't important, maybe get better price for non 611 J 
Both look same, seem to have same features, so wondered what differences if any, or if 1674/5/6 is just a re-release of previous engines, so I can buy either series with no worry.
BTW, sent note to MTH as they listed the 30-1676-1 as an HO scale engine which it is not, oops!
