Back in Feb of 2009 we did a breakdown of engines by make amongst OGR forum members at the time. 50 members replied.
The breakdown went like this:
Lionel 38.7 %
MTH 38.5 %
Williams 3.9 %
Weaver 1.7 %
K-Line 3.4 %
Atlas 6.3 %
3rd Rail 1.2 %
Other 6.2 %
I remember being surprised at how close Lionel and MTH came in.
A lot has changed in 5 years, and I wonder how a similar survey would stack up today?
I suspect that interest in MTH has waned since they have pursued the HO etc and seem to have been dormant in new O scale stuff. PS-3 is OK, but not really a whole bunch better than PS-2.
Lionel meanwhile has had big hits with such things as Legacy, wireless tether, quilling whistle, steam smoke, better sounds, better speakers, etc.
I have certainly bought way more Lionel in the last 4-5 years than MTH, probably by a factor of 10:1, for all the reasons above.
I am NOT trying to stir up yellow/purple versus orange/blue wars here; just wondering how others see it these days?
