2-mile (3.2 km) tunnel was being built. In low-speed service where high tractive effort was critical, these Decapods were successful. Small numbers of other...

They are capable of generating 109,000 lbf (480 kN) of continuous tractive effort.[page needed] From late 2001, the SD70M was produced with SD45-style...

largest tractive effort for any locomotives up to the mid-1910s. The Union Pacific Big Boy, built in the 1940s, did not exceed the tractive effort of the...

v20-710 engine. The class was stopped only with 7 units due to poor tractive effort - it provided only 560 kilonewtons, which is just 20 kilonewtons more...

expressed in kilonewtons (kN), where 1 kN = 1000 N. For example, the tractive effort of a Class Y steam train locomotive and the thrust of an F100 jet engine...

increased the tractive effort to around 38,165 lbf (169,770 N), slightly below the figure required by Pole. As a means of increasing the tractive effort to bring...

between 1942 and 1944. The J1 had over 95,000 pounds-force (422.6 kN) of tractive effort, plus an additional 15,000 lbf (66.7 kN) if the booster engine was...

151; with the new digitally controlled anti wheel-slip control the tractive effort should be brought to bear more reliably: nonetheless, some engine drivers...

These had lowered motor gearing from 62/17 to 57/22 which reduced the tractive effort, but also reduced traction motor rpm at speed and so reduced the risk...
