At the core of our mission to facilitate the resurgence of street railway as a popular form of urban transit , lies our deep seated commitment to energy conservation and the use of renewable energy sources.
The very fact that steel wheels running on steel rails encounter only 15% of the rolling resistance of rubber-tired systems represents an enormous cumulative saving in energy expenditure. This means:
This fact makes the streetcar the perfect platform for self-powered operation using sustainable energy design components on-board the vehicle.
We believe it is our responsibility to introduce sustainable design practices into the dialogue with our clients. From the basic concept of getting people out of their cars and into an attractive and exhilarating streetcar, to the idea of using renewable energy to power their streetcar, we can offer our clients groundbreaking ideas that will give their project real and unique advantages in the current marketplace.
TIG/m self-powered streetcars are designed and operate under a simple overall calculation:
On-board electricity storage + on-board electricity generation + regenerative braking = traction power + ancillary power + 30% surplus power.
By sizing the value of the first two components we can assure that the vehicles will operate successfully on any given duty-cycle without deep-cycling the batteries. When we enter into an agreement to design/build a streetcar system for a client, we offer alternative technological solutions for these components:
On-board electricity storage:
On-board electricity generation:
