DoorZigt completed all projects 31st December 2018. A period of 16 years of consultancy came to an end.
This website provides for an impression of DoorZigt's contributions to the railway sector in this period.
Please note, that contributions by Lieuwe Zigterman before the foundation of DoorZigt B.V. are not dealt with. Some examples are: BB21 (strategic study on signalling & control systems for NS), traction power supply system choice (also for NS) and the study GroeiSporen (more trains on track for Railforum).
