BTW, the gems weren't my idea and I take no credit for it. I got the idea from the original concept art overhead of New Fantasyland, which showed off what was clearly supposed to be glittering gems on the outside near the various entrances to the mine (zoom into the picture and check out the outside areas surrounding the mine shaft entrances more closely and you'll see the colored gems i'm talking about)-

It's one of the elements I was hoping would make it into the final product. Preferably done to an even greater extent than the concept art showed off. Sadly they didn't include this aspect at all, and i'm actually somewhat disappointed with how the outside looks at night to be honest after seeing numerous photos and videos of it in action after dark. All the other mountain facades have stunning colored spotlighting and are just as fun (if not better) ridden at night due to that attention to detail.
The Mine Train is lacking in that regard and doesn't feel like they did as well with lighting it at night, just some lanterns scattered about that don't help illuminate the scenery very well. Having sparkling LED-lit gemstones adorning the whole thing would have gone a long way to making it one hell of a gorgeous spectacle to behold at night. It reminds me slightly of the lovely old Main Street hub trees that were adorned with twinkling lights...
