This looks like a great way to get from Quito to Guayaquil, assuming you're in no hurry.
I went to the TrenEcuador website to see how much it would cost, but couldn't find Quito-Guayaquil, only individual segments of the whole trip -- for which, prices are very reasonable. It might be fun to do part of this just as a daytrip out of the city. Has anybody tried it?
