Rolf Stumpf's International ALCo/MLW Pages

These pages are dedicated to the finest diesel locos ever built - the ALCos and MLWs (and the numerous licensees).

Welcome, ALCo addict no. since June, 3rd 1996. Established January 1996.


Hi, I'm Rolf Stumpf, an Alcophile from Germany. Enjoy my worldwide compilation of ALCos, MLWs and licensee ALCo power.

Note: ALCoWorld is a no-profit-site and not related with a spare parts or locomotive business. Mails concerning spares or sales partnerships are a waste of your and my time...

Latest content statistics: 956 pics on 307 pages.
