This optional worksheet is designed to enable you to take the demand data associated with an origin (Entrance, train, vehicle, etc.) and fine tune it further to create train carriage distributions, services and sequences (‘continuous’ or ‘periodic’) of any services you may wish to combine. In many case you will not need to use this sheet but it can be very useful when you do.

For each origin you choose there is an ‘Origin Table’ comprising two main sections, which you can use separately or together: ‘Split into suborigins?’ and ‘Frequency based?’.

• Split into suborigins – this section enables you to divide an Arrival Profile into smaller profiles in order to model, for example, the different carriages of an arriving train. On import, a pending object will be created for each sub-origin.
• Frequency based – this section enables you to create arrival patterns based on a frequency (5 trains per hour, for example) or to set up a sequence of arrivals for different services (three express trains – one stopping service – three express trains, for example).
