A Little Guatemalan Narrow Gauge

I presume this is the same trestle near Guatemala City that is in Greg Maxwell's recent post on Pacific Narrow Gauge. This is scanned from a color slide. I wonder if the photographer got other shots of the train as it passed over this spectacular trestle? We can see just enough of the engine to identify it as Cia Agricola #180 which was an outside framed 2-8-2. I haven't found any specs. on it on-line, but sadly it is not listed in "Surviving World Steam". Hopefully someone can supply more info on this engine. Note the crew member / dare devil on the top of one of the freight cars. I get acrophobia just thinking about it. The scan is from the SVRR Archive.
