It appears that they have either fixed or taken off the train that was making the very unusal rattling sounds as it went around the track.
Anyway, I had some more thoughts on The Smiler on Saturday. When riding a coaster I like to be able to sit back, relax and enjoy the ride. You can do this on most coasters whether it be Blue Fire, Nemesis, El Toro and so on. I do not like having to hold onto the restraints when riding coasters, I prefer either arms up or just sitting with my arms in a relaxed position. However on The Smiler I always have to hold on to the restraints. I'm constantly bracing and therefore tensing my body. This isn't at all relaxing and not overly enjoyable. I have to do it though as the ride throws me around so much; this is partly due to the rattly, jolty nature of the ride and partly down to Gerstlauer's over the shoulder restraints which I have never liked. My shoulders always know when I have ridden The Smiler.
I really do think that lap bars would make it better. Ok your body may get thrown around a bit but my body and shoulders wouldn't be bashing into the restraints. I'd be able to relax a lot more on it and just enjoy what is a good thrilling layout.
It is just a shame for me that the poor build quality and poor restraints ruin what could have been a brilliant ride.
