Perhaps it is human nature to fixate on flaws rather than recognize the good in something, at least it seems to be a common practice on this forum. Lionel's recent GS-4 is a prime example. I, like many on the forum was bummed about the backwards hatch. I had the previous Legacy GS-4 (6-11127 from 2008) and I too like that whistle better than the new one.
BUT, there are several improvements on the newest version relative to the previous version that deserve to be recognized.....
1. The sound quality is more deep and rich than the previous version.
2. The background noises on this sound file add another dimension to the engine.
3. The side rods are the correct size and I like that they are blackened
4. I like the blacked out wheels (no whitewall)
5. The cab light is no longer a bulb sticking out of the backhead but rather a more discrete LED discretely bolted to the roof (in truth less a factor with the closed cab, but still a nice touch)
6. The whistle steam is a great feature AND the smoke comes out of the whistle rather than a conspicuous hole in the boiler. Lionel did a nice job of recasting the whistle to hide the hole in the boiler.
7. The Daylight logo on the engineer's side is properly oriented (it was backwards on my old engine)
8. The IR Sensor adds play value for me
9. Legacy Sequence Control also adds play value for me
Is it perfect? Well, no nothing is. But this model does represent an advancement over its predecessor. I am happy I bought this engine and that Lionel is advancing our hobby. I just wanted to post something positive about this engine as there is much about it that is worthy of praise, plus I get tired of reading all the negative posts about flaws and prices that are too high.
