[quote]QUOTE: <i>Originally posted by daveklepper</i> <br /><br />You can run heavy ore trains under 1500V DC catenary, if you have the wire diameter and substation capacity to do it. And probably fi you are using only one locomotive, it better have two pantographs contacting the wire. I suspect it was substation capacity that prevented electric locomotives on the ore trains. One ore train probably would draw about ten times the amperage that one typical passenger train draws.[/quote] <br /> <br />Well - top 1500VDC loco are about 6000 hp. 5500 tonne trains (as those ore train are) need about 10000 hp in european enviroment. Current 1500VDC catenery simply cannot cope with such load. Rebuilding it for just two trains per day is nonsense - so diesels are used.
