However, as a result of their late delivery, high axle load of over 22 tonnes (which restricted its use to only a few routes) and structural changes to rail operations, this plan did not come to fruition.

[1] They had a conical smokebox door and partial streamlining which protected the cylinders from dirt and from cooling too rapidly and, at the same time, was supposed to reduce wind resistance.

Number 10 001 hauled the E 387/388 (E 687/688) fast-stopping services to and from Münster almost without a break from 21 March 1967 to the beginning of January 1968, and for one month even had special permission to continue as far as Rheine (which part of the route was only cleared for 20 tonne axle loads).
