What ist modern steam?
Modern steam stands for a new economic and ecologic steam technology, providing the following advantages:

One man operation for steam locomotives
Remote controlled steam engine for ships
Light-oil firing with clean combustion
Low cost of ownership provides good return on investment High thermal efficiency of engine and boiler
High level insulation of boiler, steam engine and piping
Modular concept
Exchangeable parts
Up to date bearing technology reduces maintenance and protects the environment
Electric preheating device enables to put or keep an engine in steam without attendance
The enormous positive impact the modern rack steam locomotives have on the economics, can be seen below:






On 22 September 2005 the "Modern Steam am Hauenstein GmbH" has been founded at Sissach, Switzerland. The first step to be undertaken will be the development of a business plan. The ultimate aim of the company is to save rail traction on the old Hauenstein line from Sissach to Olten. The present electric traction covers its cost to only 20% and is therefore in danger of being changed to bus operation. The concept of a modern, economic and ecologically viable steam train allows higher revenue with equal operating costs, thereby significantly reducing the amount of subsidies. The line from Sissach to Olten is a good case for demonstrating such an idea, but other branch lines can be looked at as well.
