The folk over at "TrackMaster Village" have purchased and demonstrated the Real Steam Percy. Thankfully, he is just normal green and not metallic, as in the prototype photos.
I just wish the entire funnel (and water reservoir) didn't light up from outside like that. It really ruins the whole look when the engine is running. If not red, I would've expected a green light for Percy and a blue one for Thomas.
I sort of like the blue light, but do like the old one with the red too. Maybe you could easily use a red film to tint the led it swap it out? I do like the button to turn them on though. I wish it had some sort of sound, maybe a seperate switch, etc...
