Honorable Mention

commuter rail

Referred to as the town's new Metro, and even sometimes as the "subway" or "underground", Huancayo's new railway is really none of these things. Sadly, wishing does not make it so.
 It only makes you a Wanker. Or in this case, a Wanka.

Using former Copenhagen diesel commuter rail cars, the first 7 km, 7 station section of this railway will connect the city of Huancajo with the nearby town of El Tambo. A 42 km extension is planned, as well as
a 50 km second line..
