The handling and distribution of the personnel data will probably
constitute the most difficult problem during implementation

IT-plan has to be devised

strategies (Diesel versus Natural Gas)
Overview of cost comparison
Additional investments until 2018 versus Diesel
Buses: ca. 7,1 Mio €
Infrastructure: ca. 2,5 Mio €
Health and safety: ca. 0,8 Mio €
Total ca. 10,4 Mio €
Additional annual costs until 2018 versus Diesel
Capital costs buses: ca. + 0,80 Mio €
Maintenance costs: ca. + 0,60 to + 0,80 Mio €
Fuel costs: ca. – 0,40 Mio €
Capital costs infrastructure: ca. + 0,25 Mio €
Running costs infrastructure: ca. + 0,28 to + 0,33 Mio €
Costs quot;health and safetyquot;: ca. + 0,14 Mio €
Costs due to adjusted processes: ca. + 0,02 to + 0,08 Mio €

From an economic perspective, a technology switch towards
buses powered by Natural Gas motors is not recommendable
