00 track finalisation - Where to isolate?

Surfing the wave of a functioning layout to look at the 'nice to haves' ...

 

Currently trains can be parked in the sidings or the lower space between points 9 and 10, but there are a couple of glitches that prevent more flexibility:

 

Between points 8 - 6. It would be nice to have a train waiting at the platform while another could shunt out of the sidings onto track 2, however this is currently impossible as the LH Point 8 and RH point 6 means that the track between them is always live. If this was isolated would the power be interlocked with points 6? It would make sense but adds complexity and would break the continues loop of current. Is this worth it?

 

Between points 8 - 10.  Currently, if there is a train parked between points 9 and 10, on the lower route, another train can't run from 8 to 10 on the middle route as both points 9 are linked and to set the route for the middle would also power the parked train from behind.  I could isolate the lower route just after points 9 and link a power source to points 10?

 

Additional siding from points 10 parallel to the bottom of the board, which would give a refuge for a loco and allow an exchange of carriages or wagons. Would it bring any useful operational benefit?  

 

Maybe overthinking this

Ideally you would have installed isolated sections in the places that you want to park trains and feed these through on-off switch.  I guess the question is how easy it would be to add a few insulated rail joiners at this point in time?

If you had a passenger train between 8 and 6 then it is unlikely a freight would precede it and therefore your first scenario seems void in real world situation. To shunt freight out in front would be improbable. More likely a head shunt (siding in the opposite direction at the entrance to a fan of sidings) for the sidings created by 2 through 4 would be provided with a LH? connection creating a line parallel to the track 6 to 11.

 

Sidings in the bottom right could work well and add interest in the opposite direction main running line.

Nothing is permanent yet and modifications can still be made. I think I'm sold on the additional siding on the bottom right and someway of isolating the bottom siding so that a train can be parked there and another change from the Track 2 to 1 via the middle route. Jury is still out on modifying the station area. 

 

Signals and uncoupling are my next targets to get right before really hard-wiring everything

I think i have the answers to the problems that i have invented..!!

  • Separate points 9 to individual control so that the middle and bottom lines can be isolated / electrified independently 
  •  Add an extra siding next to points 10, which can be electrified by opening the newly separated points 9
  •  Add an insulator after points 8 so that the section next to it is only electrified through points 6, plus add a feed at points 6
