For the ultimate in information on the Columbian Railways, you need to find "La Mula de Hierro" (The Iron Mule), by Gustavo Arias De Greiff, published by Carlos Valencia, 1986 in Bogota. ISBN # 958-9044-26-3. The address is Apartado Aereo 22197, Bogota, Columbia.
I saw a copy on the shelf at Motor Books, in London, England about a year ago, for about £25. I was fortunate enough to have been given a copy by a good friend, who picked one up in Bogota a number of years ago. I'm really sorry I never got down there, they had some fantastic engines. Get the book, you won't be sorry! It's in Spanish, but you can figure out the data section, no problemo!
