Been able to experiment with materials to see which works and which doesnt
My layout isn't modeled on anywhere in particular. it is about 4m long and about a Metre wide. It Consists of a tram line (70% is double track soon to be 100% double track) with 3 tram stops. Being the 2 terminuses (Surrey Hills and Molesworth) and another stop in the middle (Albion park / Riddles lane). The Layout Also has a single (soon to be double) heavy rail line with a Siding which Crosses the tram line... Both the tram and heavy rail line are operated via one DC Power mite Controller but both tracks are isolated from each other (meaning the tram can go without the heavy rail vehicles moving with it)
The Heavy rail at the moment is a Passenger service with stations serving Moleswoth and Surrey Hills, The siding is located at the Molesworth end and also has a Docking Platform
My latest project is returning signals to the heavy rail section (which includes installing the LED type Lights) Which has seen Several LED's Blow and One Splt in half cause somoene forgot to place a resistor in the circut
My Working "vehicles" are a Converted Passenger car which i have painted in Admet colours (engine stolen form a Lima loco) there sis still alot of work to go including new "fronts" for her, and a Tram With a rather dodgey looking panto Also taken from the Lima Loco and a Union Pacific Loco (kinda looks like a C Class). i have 2 SW6 Trams which are both unpowered, My Overhead is Minor detail which is just white cotton, (must buy black)
this layout is nowhere near Complete but is getting there
A Diagram is included

Insanely Stupidly bright LED

My Tram and the ACPV pose for a photo at the crossover. SW6 1020 can be seen in the backround
My tram flys past the camera running late returning to Surrey Hills
My tram and SW6 1020 at Albion Park / Riddles lane Stop
SW6 1020 Awaits clear track as the ACPV crosses over form the docking platform
SW6 1020 and My tram look on as the ACPV crosses overtoward the Docking Platform, the blue reflection is the LED Signal
The Signal at Surrey Hills
I wear my sunglasses at night: the ACPV parked at the Docking Platform while the LED Signal Lights up the room
I like the whole overhead idea, certainly something you don't normally see on layouts. And the heavy/light rail interaction is a great idea! 
Better get those heavy rail maintenance guys going, sounds like they've been slacking off a bit...
