Undertake and report on a risk assessment of the introduction of tram train vehicles onto the existing main line tracks between the two cities, as detailed in the scenario above.

A Local Passenger Transport Executive (PTE) is looking at expanding its existing tram system to include a link to an adjacent city. There is a heavy rail route between the two cities and that runs alongside one tramway line. In order to save building a new tramway line, the PTE wishes to run trams on the main line tracks between the cities. For this service the PTE will procure new Tram Train vehicles.
The tramway uses low floor three segment trams with platforms set at 375mm above rail level and it is electrified at 750 V dc using overhead lines. The twin track main line is not electrified and carries 5 freight trains a day and a half hourly local diesel service in each direction for about 18 hours of the day.
The PTE wishes to have a 20 minute interval service connecting the centre of their city with the adjacent City’s main station (2½ miles from the junction with the tramway) along the main line and then on to a new turnback stop adjacent to the mainline at the retail park (a further 1¼ miles).
Your task:
Undertake and report on a risk assessment of the introduction of tram train vehicles onto the existing main line tracks between the two cities, as detailed in the scenario above.
Your introduction should include an explanation of the method of risk assessment you followed.
The risk assessment should include identification of risks, a simple 3-level assessment of severity and likelihood and identification of proposed mitigations. You might find a table added to your text will assist you with this.
You should conclude commenting on the viability of the proposed introduction of this service.
Additional Guidance:
You will need to research existing tram train systems in Britain and overseas to identify the basic operational and engineering requirements.
Your identification of risks should make reference to at least three legal, procedural or standard requirements that cover tram train, passenger, freight and national rail systems.
