From 2013 until today:

Milestones in developing the E³ technology


Start of production of further E³ machines for operation in Italy with dual supply voltages from the overhead line (25kV/AC and 3kV/DC): Unimat 09-32/4S Dynamic E³ and Unimat Combi 08-275 E³


Testing the HTW 100 E³


Successful testing of the travelling and working operation of the all-electric E³ drive concept of the new Unimat 09-4x4/4S E³


Comprehensive tests and analyses (fire protection, Climate Wind Channel, TÜV, risk analysis, functional safety, etc.)


Introduction of the HTW 100 E³ at iaf: battery power for all works on the overhead line


iaf International Exhibition for Track Technology in Münster: Introduction of the world’s first fully electrically powered tamping machine - the Unimat 09-4x4/4S E³


Start of production of the HTW 100 E³


Delivery of the Unimat 09-32/4S Dynamic E³ universal tamping machine to Krebs Gleisbau. Machine approvals for operation in Germany, Austria and Switzerland


Start of the design and engineering of the HTW 100 E³


Project planning for a hybrid vehicle for works on the overhead line with battery technology. Development according to market requirements: energy-efficient, quiet, low in emissions, environmentally-friendly, user-friendly


Preparation of an extended E³ concept: electric drive integrated into the bogie and electric drive of the work units


Completion and supply of the first two E³ machines. Live demonstration for 500 experts at the convention of the Austrian Society for Traffic and Transport Science in Salzburg.


Start of production of the first E³ machines: 09-4X E³ Dynamic Tamping Express 4-sleeper tamping machine and BDS 2000 E³ ballast management system


Start of the project and conception of an electric drive shaft


Selection of machine models with hybrid drive concept


First talks led to the decision to implement a hybrid drive concept with hydrostatic drive. The E³ brand was created.
