The Siemens-Schuckert-Werke (SSW) made the E 44. It was the standard e-loco for passenger- and freight service and the DRG ordered it in great numbers. The experience gained in making three pre-series machines was used for optimizing the construction. Because the E 44 meets all requirements, it was used on all routes of the DRG. As late as the beginning of the 80s you found locos of this type in service at the DB and the DR.
We made the E 44 of the DB and DRG with short roof, sixteen sandboxes and pantographs of the type SBS 10, the DB E 144 with longer roof, eigth sandboxes and indusi and the DR E 244 painted green/red with black chassis. Moreover we made the E 44.5.
