Systemwide uses a variety of analytical techniques and tools in
providing strategic advice to our clients. We are leaders in developing new
scientifically based methods to determine rail network capacity.

Our Techniques |
Application |
Software |
Parametric Analysis
applies mathematical methods to
determine network capacity |
- A quick way to review the capacity of lines, junctions, stations and yards and gain
an initial appreciation of the key issues affecting a network
|
|
Train Performance Calculation
utilises sophisticated software that
accurately calculates train running
times and energy consumption,
particularly suitable for long and
heavy freight services in complex
topology |
- Calculates travel times very accurately using
different equations based upon detailed
infrastructure and train performance parameters
such as braking, resistance and acceleration
- Treats trains as distributed loads rather than point
loads, which is important for long, heavy freight
trains on hilly terrain
- Handles curve resistance as part of its rolling
resistance calculations, which is important for
freight trains on curved tracks
- Estimates accurately the energy consumption for
both diesel and electric powered rollingstock
- Verifies the feasibility of operating freight trains
on steep grades
|
|
Static Train Graph Analysis
uses graphical techniques to analyse
the interaction between trains on
track and junctions of different
configurations |
- Provides a detailed assessment of the impact on
capacity of: trains of different performance and
stopping patterns; the track, signal and junction
design; and scheduling constraints
- Used to develop potential capacity improvement
options that are based on a sound understanding
of the network’s capacity and its constraints
- Provides a base timetable for future scenario
analysis
|
|
Dynamic Simulation
is the most accepted method to
predict the future reliability of
railways based on detailed simulation
of many days of operation |
- Allows a comprehensive validation of proposed
capacity improvement or infrastructure solutions
and their operational reliability
- Creates detailed infrastructure design parameters
for the proposed capacity improvement solutions
(e.g. the exact length of a 3rd track, the signal
placement)
- Allows the capacity benefit of different
infrastructure and operational options to be
quantified and compared
- Measures the capacity impact of reliability
improvement measures such as delay incident
reductions and management of dwell times at
stations
|
|
Train Load Predictor
is a proprietary Systemwide product
that estimates the number of
passengers on each train for a future
timetable |
- Allows a service plan to be created from forecast
patronage data which minimises the number of
trains required
- Provides scientific verification of the efficiency
and effectiveness of proposed service plans
(strategic timetables)
- Optimises timetables to utilise resources optimally
and avoid over and under-crowding of trains
