History

SM40 were imported for the first time from Hungary in 1959, after tests at the distance of 2,185 km with cargo load of 156 t.

The first name for this loco was Lwe58, and in 1960 it was changed to SM40 (according to RN-58/MK0001 regulations).

Items delivered from 1961 had a few modifications, and a different code-name SM41.

gollark: I count use of regices as HTML parsing still, if a dark-god-invoking form of it.
gollark: Some even require running JS.
