Oil-fired Mikado originally delivered to the FC Lima a Lurin, which operated between 1918 and 1964. The Alco design had a relatively large cylinder volume and low boiler pressure, coupled with the large piston valves, suggest a design intending to extract as much as possible out of a lungful of steam without taxing the maintenance facilities unduly.
The trenesdelperu blog commented in June 2009 that the railway's demise was due to an "incomprehensible anti-rail policy" (incompresible politica antirriel ). The author notes the railway's principal role in serving a section of Peru's Amazonas State was demonstrable and laments that a lack of vision prevented any possibility of doing so now once the railway was abandoned, the rails pulled up, and all of the material sold by the pound for scrap.
