I didn't see anyone post what might be the BEST news related to the Atlas move:
In the USA, Atlas is the second oldest manufacturer to Lionel. Also I THINK they are still family-owned. From this one might assume that the Atlas people have a grip on the trends. IF so- you could surmise:
1. No matter how little that investment might be NOW as compared to what it might have been to buy all of MTH as an entity a few years ago, the fact that they were willing to invest ANYTHING in O and that a very knowledgeable group of people are willing to "put their money where their mouth is" says they think that O is NOT dead. If they really thought the O hobby (or even the MR hobby as a whole) was totally "dead"- they would not have spent ANY money on it. Therefore one might assume that they think there IS a future on O Scale. But that is and will still remain a fragment of the business available in HO and N.
That's the good news.
2. The fact that they did not buy the RailKing ("traditional") sized line, tells me that they see O SCALE as being the part of the hobby remaining long-term, but not the O Gauge part.
They are and have been a scale model producer, in every scale. The MTH line gives them a big line of O Scale. And immediately a big line of accessories for all of the O market.
Regarding control systems- most likely, Atlas will phase out of Lionel Legacy/TMCC, etc., and move on with DCS, as it IS more similar to DCC than it is to the Lionel systems. Whereas, Lionel SEEMS to be moving toward "non-handheld" methods of control?? That is the bad news for those of us committed to Legacy and TMCC.
