The company’s own annual production amounts to approximately 2,000 gigawatt hours. SBB produces a large portion of Switzerland’s traction power (16.7 hertz) as well as a portion of regular electricity (50 hertz) with 13 own power stations and frequency converters. Important elements include technical innovations for rolling stock, fixed installations and buildings, energy efficient service planning, as well as innovations in railway production. Some 25 specialists from various disciplines are currently responsible for the implementation of over 250 economically viable measures. To reach its ambitious energy-saving target, SBB is reviewing the savings potential and implementing energy-saving measures throughout the company and along SBB’s entire value chain.
This is equivalent to 600 gigawatt hours or the annual energy consumption of 150,000 households. Within the framework of its energy strategy and energy saving programme, SBB is aiming to reduce its anticipated annual energy consumption for 2025 by 20%. From 2025 trains are set to run on electricity generated entirely from renewable energy sources.Īt the same time, however, SBB’s energy consumption is rising due to the expansion of services as well as heavier power-hungry rolling stock. With an average of 90% hydropower in the traction power mix and a completely electrified network, SBB is one of the most environmentally-friendly railways in Europe. Swiss Federal Railways AG (SBB) transports 1,210,000 passengers and some 205,000 tonnes of freight every day in a manner that is both energy efficient, climate-friendly and safe. Rail is the backbone of sustainable mobility in Switzerland.

This software calculates an energy-optimised driving profile for all trains that also has a positive effect on timetable stability and punctuality. Adaptive control (ADL) holds great savings potential. For this purpose SBB has implemented a comprehensive energy saving programme. If the IMAGE_FILE_LARGE_ADDRESS_AWARE flag is not set, each 32-bit application receives 2 GB of virtual address space in the WOW64 environment.SBB is aiming to save 20% of its anticipated annual energy consumption for 2025, equivalent to 600 gigawatt hours. If the application has the IMAGE_FILE_LARGE_ADDRESS_AWARE flag set in the image header, each 32-bit application receives 4 GB of virtual address space in the WOW64 environment. The amount reserved depends on the processor more is reserved on the Intel Itanium than on the 圆4 or ARM64 processors. In addition, some amount of address space is reserved for WOW64 itself and the data structures it uses. However, 32-bit applications may not be able to create as many threads under WOW64 as they can when running natively on x86-based systems because WOW64 allocates an additional 64-bit stack (usually 512 KB) for each thread. Therefore, 32-bit applications can use a larger number of kernel handles and window handles. WOW64 enables 32-bit applications to take advantage of the 64-bit kernel. WOW64 increases the size of the application's working set. This is not the case for the 圆4 processor. This can adversely affect the scalability of Terminal Services on certain processors. This is due to the native 8 KB pages on the Intel Itanium, which complicates the emulation of the native 4 KB pages on the x86 architecture (more pages are marked as writable all writable pages are private to the process). On the Intel Itanium processor, WOW64 adds significant overhead if two or more instances of the same 32-bit application are running concurrently. NT kernel functions are intended to be called infrequently. This overhead is small compared to system calls to the NT kernel. On the Intel Itanium processor and any ARM64 processors, more software is involved in the emulation, and performance suffers as a result. Therefore, execution speed under WOW64 on 圆4 is similar to its speed under 32-bit Windows.
On the 圆4 processor, x86 instructions are executed natively by the processor. Instruction emulation is performed on the chip. Performance and memory consumption under WOW64 are determined by the following factors:
