The new line would involve new track from Granton Square to link up with the existing line through the city centre and then more new track down the North Bridge corridor to Cameron Toll and on to the Infirmary and BioQuarter.
The section between Crewe Toll and the city centre could follow one of two routes - one of the key issues in the 12-week consultation now under way.
The tramline could use either the Roseburn Path pedestrian and cycle route, linking up with the existing line before Haymarket; or the alternative option of going via Crewe Road South and Orchard Brae, crossing Dean Bridge and joining the existing line at the west end of Princes Street.
Here is a look at the proposed stops along the way - including both the Roseburn Path and Orchard Brae option. The pictures do not necessarily reflect the precise location proposed for each stop.
5. Roseburn Path route: Crewe Toll
Crewe Toll is where the two alternative routes diverge - the Roseburn Path option would provide a fully off-street tramline from Crewe Toll to Haymarket. | TSPL Photo: Greg Macvean

6. Roseburn Path route: Telford Drive (for Western General)
On the Roseburn Path route, the nearest stop to the Western General Hospital would be at Telford Drive. An upgraded crossing is proposed at Telford Road, makng it easier to get from the tram stop to the hospital and cutting the walking time from 8.5 minutes to five minutes. A more prominent hospital entrance would also be created, with better access to major facilities. | Google
7. Roseburn Path route: Craigleith
A tram stop would be provided at Craigleith to serve the local community and nearby retail park. Proposals at the stop include a plaza, playground and improved access to the Craigleith retail park. | Google
8. Roseburn Path route: Roseburn
The next stop would be Roseburn. Between Craigleith and Roseburn it is proposed the route would be single track to minimise the impact on landscape and ecology. A previously proposed tram stop at Ravelston Dykes is now omitted for the same reason. Beyond Roseburn, the line would continue along the Roseburn Path to join the existing line near Russell Road. | Google
