There is one trend I can see being made. G scale trains may eventually be described in thier scale ratios rather than using a universal gauge letter such as G scale or Fn3 scale. I believe one reason for this is that manufacturers and people want to sperate themselves from the G scale toy world like New Brite battery operated trains. How many people have you told you model in G scale and the first thing they think of is those department store battery operated trains that little kids were palying with. Although the NMRA has officailly named 1:20.3 scale ratio Fn3 gauge and 1:32 scale ratio G scale, I think it's too late for them to get involved to say what gauge should be standard. As DragonfyreGT stated, they wanted nothing to do with G scale in the begining so why bother us now. I have noticed more manufacturers getting away from calling thier trains G scale or universalizing them as such. Both USA Trains and Aristocraft have been officially marketing thier trains as 1:29 scale ratio trains and not G scale. I seen it said somewhere on the board this is due to that fact that the NMRA doesn't recognize 1:29 scale ratio as G scale, well this may be true, I don't know neither do I care. But what I do think is that having a standard practice of labeling trains by thier scale ratios will be common place for all manufacturers and the only ones left calling themselves G scale will be the battery operated toy train manufacturers such as New Brite. So in my opinion, the new trend will be labeling trains by thier scale ratios and not by thier gauge, at least in G scale Pictures #1 & #2: USA Trains has been labeling thier products 1:29 scale ratio since the introduction of the 55ft series freight cars in 2006. They also labeled the new sd-70MAC locomotive as 1:29 scale ratio Pictures #3 & #4: Aristocrafts label looks a little confusing and seems to be contridicting in itself. You will notice that thier label says Gauge #1 and 1:29 scale ratio. We all now know that gauge #1 is 1:32 scale ratio. Well, if you think about it, they are really giving you the info of what track this freight car will ride on which is Gauge #1. I think this is another reason why stating gauge size should be dropped because you can have a gauge #1 train and Gauge #1 track. In the future we will probably see 1:32 scale ratio labels instead. This way Gauge #1 would only describe the track and thats it. MTH for example still describes thier trains as Gauge #1 instead of 1:32 scale ratio. This is probably due to the NMRA ratings which they would follow since how they are a heavy O scale manufacturer. They are still fresh to the G scale market and may eventually change the way they label thier trains one day.
