Transportation and industry have played an important role in the development of Marienfelde: Since 1875 the Dresden Railway, a main North-South line entering Berlin, passes through Marienfelde.
It is currently served by the Berlin S-Bahn commuter rail network at the Marienfelde, Buckower Chaussee and Schichauweg railway stations.
The re-development as a long-distance track is planned.

The parallel Royal Prussian Military Railway (Königlich Preußische Militäreisenbahn) passed through the Marienfelde area on its way from Berlin to the town of Zossen.
Between 1901 and 1904, the track was electrified and used as test track for high-speed locomotive testing.
Ten kilovolt, three-phase alternating current with a frequency of 50 hertz was transmitted over three overhead wires, strung one above the other.
Experimental electrical locomotives reached speeds of up to 210.8 km/h (131 mph) on the track.

Near the end of World War II, as part of the Elbe-Project, the world's first high-voltage direct current transmission lines were built from a power plant in Dessau, on the Elbe river, to Marienfelde.
A substation was located in Marienfelde converted the direct current into alternating current.
However, developments in the war prevented the project from ever becoming operational.

Today, Marienfelde comprises several industrial parks such as the former Daimler Motoren Gesellschaft assembly plant opened in 1902, today operated by Daimler AG.
Other main employers include IBM and Stollwerck; as well as branches of the Federal Ministry of Food and Agriculture, the Federal Office of Consumer Protection and Food Safety, and the Friedrich Loeffler Institute.
