As the track runs between the pillars underneath the freeway just outside San Francisco station, the external cameras are locked out. Presumably this is because that area is classed as a tunnel. I love using the external camera in that area and I can’t in TSW2. There is no reason not to allow external cameras there. External cameras being locked out of tunnels and elsewhere on all routes is the biggest disappointment in TSW2. Please re-enable external cameras in tunnels for the love of looking at trains enter and exit tunnels and pass between pillars, and for disappointed screenshot lovers everywhere.
