Lineside Location Cases - Devon / Somerset

[Revolution Mike B]

Would anyone be so kind as to tell me what type of Location Cases I need for Oak Road - my modern image 2010 ish to present layout based in Devon / Somerset? 

 

I have no idea about these boxes and my laziness in trying to find out more info on the web has got the better of me (at least I'm honest!).

There is a leading crossover on the main line which then spurs off to a a bay platform and two road virtual quarry (as shown below) and a 4 aspect signal at the end of each platform (with the exception of the bay which has a 3 aspect signal). It is assumed that the signal for the downline for the crossover is off scene.

 

Any advice would be most welcome as to the placement of the cases and other associated boxes / equipment / troughing relevant to this particular region.

 

 

Thanks

Mike
