Railfans from Switzerland, Germany and Austria of the Tanago tour are waiting for the loaded sulphuric acid tank car train of the FCAB, which is tackling the grade of the Cumbre pass on the way from Mejillones to (probably) Chuquicamata. Pulling are GL26C # 2006 (former Queensland Government Railway QGR # 2108D built by Clyde in 1971) and GR12UM # 1414 and # 1413, former Canadian National Railway EMD NF210 # 936 and # 926.
