My son would LOVE the London underground one - he's a real train/tube geek (and has done the Tube Challenge)... expensive for a silly toy though!
A BART driver once told me that the "zones" for train control on the blue line between Bay Fair and Dublin/Pleasanton are huge, like miles. This shows how true that is. It's 14 miles / 23km between those stations by car, and only 6 LEDs. No wonder the trains always seem to get hung up out there even though there's no train in sight. Neat product!
