An investment in the development of public transport is primarily an investment in the environment. The saving is obvious in everyday situations, but let us illustrate: 70 trams would be needed in order to transport 20,000 fans to the sold-out stadium at Letná in Prague. If the fans were to drive their own cars, 4,000 cars would be required, even though there would be 5 passengers in each car.
Further evidence of the importance is the irreplaceable role of the Prague metro - using cars renovated in Škoda Transportation, lines A and B carry 680 thousand passengers every day. Try to imagine the same number of people using cars. In addition to the economic benefits public transport reduces dependence on fossil fuels, protects the environment and improves our quality of life.
Škoda Transportation is also trying to reduce the life cycle costs of vehicles (LCC-Life Cycle Cost). There is an assessment of the costs associated with the acquisition of a vehicle, its operation, repair, maintenance, and disposal. Our company looks at the problems of the management of vehicles from a long-term point of view. We are trying to make most things with long service life and in such a way that they are maintenance-free.
An assembled steel cabin module with high impact resistance (meeting requirements of EN 15 227, scenarios 1-4) is used in new products of the Škoda Transportation group in accordance with the new legislation of interoperability (TSI). At the same time its technical design minimizes damage to the vehicle body itself and allows its replacement in the case of an accident. During development reduction of costs for corrective maintenance, which are involved in the total cost of LCC, was an important factor.
In addition to a functional quality management according to ISO 9001 and IRIS (International Railway Industry Standard) Škoda Transportation has implemented also the RAMS system which includes:
- Operational dependability (RAMS):
- Reliability (probable occurrence of failure during operation)
- Availability (ability perform a function/remain in operation)
- Maintainability (ability to be restored/maintained)
The RAMS management affects all stages of a vehicle life cycle, during which RAMS analyses, for example the FMEA (Failure Mode and Effects Analysis), FBA (Functional Block Analysis), risk analysis, etc. are processed. Reliability parameters, such as availability A, MTBF (Mean-Time Between Failures), MTTR (mean-time to recovery), etc., are predicted, evaluated and subsequently validated for a vehicle and its components.
The evaluated RAMS parameters are also used during the actual design or manufacture of vehicles, optimization of reliability and maintenance cycles. This process leads to continuous increasing of the reliability of products from the Škoda Transportation group.
Strong emphasis is also on supplier selection and demands are placed on the reliability and safety of individual subdeliveries. Railway transportation is, of course, safer. Today’s trains meet strict crash norms, they ride on a track with controlled traffic and they have modern safety equipment. Transport under electric tracks is also strategically stable and it can use energy from many sources, including renewable sources.
