I just purchased the MOW legacy boom car that appeared in the Lionel 2014 V2 catalog. I think it was finally released last month. I'd looked for the TMCC Union Pacific version for more than a year on eBay but never came across one. But the more I thought about it, the more I figured the MOW version would be a better fit across the lines I'm interested in (Union Pacific, Missouri Pacific, Kansas City Southern) since it would be more generic. And the legacy version in yellow may be a better bet for weathering treatment than the TMCC MOW versions that were in black. No legacy engines yet, only TMCC ones. So this will give me a way to actually use the quilling feature of my Cab2.
It seems so odd to me that Lionel has once again released the boom car and crane car separately. The sounds in the boom car are matched to the actions of the crane car. Selling them separately would seem akin to selling the UP Challenger as a separate steam engine and a separate tender. All the more so when Lionel isn't releasing them together. The crane counterpart to the boom car now en route to me isn't set for release until May of this year according to the current Lionel shipping schedule. Here's to hoping it actually ships and I don't wind up with an orphaned boom car making sounds for a non-existent crane.
My eight year old son thought the TMCC crane/boom car combos on the youtube videos I showed him were just AWESOME!
