Construction
The Kriegslokomotiven were kept as technically simple as possible and the use of imported materials (particularly copper) was generally avoided. For example, German electric locomotives were given aluminium windings in the traction motors and transformers, and the steam engines had steel fireboxes, hence the name Heimstofflok or 'home-grown loco'.
The manufacture of electric locos as Kriegslokomotiven has to be seen as a special case, because they could only be used in the core network where there was the working infrastructure able to supply the current: power stations, overhead transmission lines, electricity substations and catenary. As a rule, locomotives were preferred that were dependent on additional infrastructure as little as possible.

Famous quotes containing the word construction:
“When the leaders choose to make themselves bidders at an auction of popularity, their talents, in the construction of the state, will be of no service. They will become flatterers instead of legislators; the instruments, not the guides, of the people.”
—Edmund Burke (1729–1797)
“There’s no art
To find the mind’s construction in the face.”
—William Shakespeare (1564–1616)
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
