Nope, absolutely not. No crossover beyond St. James. If you go about 50M beyond St. James Station there is rather a large wall.
The only crossover is an 'X' on the Monument side of St. James so a train from Monument into St. James is able to arrive into either platform and hence depart from either platform to Monument. When the North Shields shorts were running, the original blue line, both platforms were used but now maybe only one is I guess.
Yep there is no crossover as Flymo states. Both platforms are still used, during peak periods and evening there will often be a train in both platforms due to the timetable and driver turnaround time.
All the signals from Monument to St. James, apart from the starter from Monument are approach release. The 'clear' from Monument heading to St. James is yellow and then slow running is required to allow the (2 I think) signals in between to release from red to yellow. The last signal has a '1' or '2' above it to indicate to the driver to which platform at St. James (s)he is signalled. Even after passing the last yellow there is a (again I think, although I may be a bit off) 20 km/h speed limit over which an alarm goes off in the cab and the driver MUST reduce the speed below the alarm trip speed otherwise the brakes WILL apply. This is all to do with various regulations brought into being after Moorgate. If you have the time or inclination please take the second man's position at the front and it will tell you all you wish to know.
Yep, correct with the signals and the 20km/h speed limit. The 20km/h speed limit is in entrance to the station, this then reduces to 15km/h at start of platform and 10km/h half way along platform. There is no alarm in this case if a driver is overspeeding, any overspeed causes an emergency brake application.
The alarm you refer to may be the drivers safety device. A driver is required to re-make the lever/handle every 45 seconds. For example if a driver was unfortunate to collapse whilst driving train and he collapsed on lever causing the train to continue in power after 45 seconds an audible beeping happens and if handle is not dropped and remade a full disc brake application is applied.
Many moons ago I was in the second man's position and we had a red light beyond Benton heading for Shiremoor. There was no intermediate stations then. Anyway after standing at the red light for a minute or two and contacting control the driver was given permission to pass the signal at red but because of the safety systems the whole trip from Benton to the next signal was at 20 or so km/h with a little alarm going off if the driver exceeded that speed. A swift brake application brought the speed down so the alarm went off but the whole section took a bit of time and was very interesting.
Whenever passing a signal at danger with permission, you have to override. -Over-riding causes trains to be limited to 30km/h until passing the next signal capable of showing a danger/red aspect. Speed limit indicator is illuminated on desk, if a driver were to go above 30km/h then an audible warning is given with a few seconds to reduce speed, if not reduced emergency brakes apply.
Lastly. I have seen in my time a Metro train beyond St. James but I seem to remember this was when they used single Metrocars in evenings and on Sundays and one unit was kind of nudged up to the friction buffers beyond the platforms. I have absolutely no proof if this or photos to back it up but I remember seeing it a few years ago, maybe 1990 or so.
Not used in recent times, or as much. They used to run trains upto buffers for extra pick ups because of special events like concerts or matchdays when St.James station would be very busy obviously.
Hope that helps

Hopefully someone will have some knowledge of workings before my time! St James is the terminus of the Yellow line, and has two platforms. Normally, a train will arrive from Monument and sit in platform 2, going out the same way. However I'm sure I have seen at least once, a train continuing down the tunnel (opposite direction to Monument) and using a cross over (I think) to get to platform 2 (when it could have just used the points at the entrance of the station to get there). Now my memory is hazy, and this was a good few years ago now, so I think there may have been a problem with the points at the entrance, so this movement was needed to ensure the train was on the right side when going back to Monument.
Could possibly have been a points failure like you said, or maybe there was a failed train on monument or manors platform. If any of them were the case then with permission a train could go facing road through to Monument and Manors whilst picking up passengers. There is a crossover prior to Manors (between Byker viaduct and Manors tunnel entrance), a train could then be signalled and put through onto correct road and continue onto Byker as normal.
