Not good english

  • an early post-war loco?

Change

Tractive effort

[edit]

Please the tractive effort is 145 kN cont. and it is 178 kN from zero. The original spec here

http://web.archive.org/web/20070911210603/http://www.kolej.pl/tabor/ET21/dane_tech.html

gives the values in kg, which is technically incorrect. You have to multiply by 9.81 to arrive a kN. google translate handles this incorrectly. 70.137.130.74 (talk) 11:06, 4 January 2012 (UTC)[reply]
