The whole route to Fleetwood will reopen when the upgrade is complete.
There are plenty of commuters between blackpool and fleetwood that will benefit by the modern trams and stops.
The heritage trams will still run in the summer so everyone is happy
There have been proposals for extending the route up the talbot gateway to the North train station and / or using tram / train technology to link into the Network Rail infrastructure at the pleasure beach.
Alternativley there is a scheme to reopen the old fleetwood to poulton le fylde railway as a light rail link as well....
All things a possibility
