I use it, along with Ross and the now-defunct Curtis and ROW - all similar. My favorite.
Just make sure you paint it; nothing ruins a nice Hi-Rail layout like 50's-bumper-chrome-looking rails; I don't know how the guys who do this can't see it - great scenery and RS and locos and buildings - and then that Silver Surfer track. Yow.
I spray mine with hardware store camo brown flat before I lay it, then sanding-block the railheads the next day. Most real track I see here in the Southeast is something like a warm black-brown anyway. It can vary by region, soil, ballast type, weather.
