Pictures I've taken of the in-progress layout of Dave T. A good friend who's allowed me to document the building of his railroad empire.

Layout Specifications (as of April 2010):
38’ x 70’ - HO scale, freelance.
Layout height 46” to 102”.
Mushroom design with 39” raised walking platform for the upper level (completed 06’).
L girder bench work construction.
Upper deck suspended by 5/16” threaded rods (completed 06’).
Roadbed is 5/8” ply with homasote. 60’ experiment with splined masonite(completed 09’).
1700’ - Mainline loop to be operated as out and back (completed 10’). Designed such that mainline can be separated into 4 separate loops (Operational loops – 1st 07’, 2nd 08’, 3rd 09’, 4th 10’).
12 - Industrial switching areas with several stand-alone sidings for a peddler. (3 Operational)
4 - 70’ Offline storage tracks for guest trains between operating sessions/shows (completed 06’).
3 - 17’ Interchange tracks to interchange with the Central Penn and South Penn Railroads (completed 07’).
16 - 17’ staging tracks hidden under yard (completed 08’).
15 - Classification tracks holding 30 - 36 cars each will make up the main double-ended yard.
12 – Arrival/Departure tracks to keep classification yard flowing.
130’ turn table with 8 stall roundhouse.
Track is code 83 for the mainline and code 100 for hidden staging. Total track laid 3450’.
Most turnouts will be hand laid and use slow motion switch machines with constant voltage circuits.
DCC control – Digitrax / EasyDCC (boosters).
Signaled with a simplified PRR style signaling showing occupancy only.
Car card system will be used for operating sessions.
Dispatcher controlled train movement with dispatchers booth under steps (80%).
