The railway room is approximately 17ft3 by 9ft9.

First up, the entire plan, without annotations showing the extent of the layout.

The fiddle yard is along a short wall, 12 inches deep. In front is a small rural terminus, roughly 3.75 inches lower and again 12 inches deep. Maximum train length is 36inches, which is roughly 6 N Gauge mark 1s.

 Along the top wall is a Settle and Carlisle inspired scene with the line emerging from the fiddle yard, splitting into the double track station off scene, a Kirkby Stephen style goods facility and then across a viaduct into a tunnel. 

Next, the line crosses the railway room entrance door. This door open sout the way.  A lift out section is envisioned with a cameo scene so that anyone opening the door, with the section in place sees a scenic diorama rather than the back of a board or a hidden railway section.  It also eliminates dealing with the unsightly joins if the section were part of the main scene.  This would be practically the only part of the railway room with hidden track when viewed from inside the room.

The line then passes over another short scenic section, possibly another viaduct and then into a tunnel for the 90 degree turn into the terminus section.  The approach track may be on a ledge as it traverses sloped terrain before arriving at the opened out level area of the station.

A line extends out of the fiddle yard in opposite direction, passing and descending behind the terminus board, descending along the door wall and under the intermediate station board to emerge 3.75 inches lower at the rural terminus station.

The same drawing with annotations, most of which is self explanatory.  The Turnouts will be controlled by MegaPoints equipment and momentary push button switches.  Train control is by NCE DCC, with plug-in terminals strategically placed around the layout. I've still to decide if signalling will be by semaphore or colour light signals. 

Whilst the line will be operated primarily by diesel motive power, principally type 2s, steam still exists in medium sized form, such as class 5s and B1s.  A shed and turntable is provided at the terminus for light turnaround maintenance.  Co-housed is a diesel fuelling point. 

The Terminus station tracks serve as follows: 1 & 2 Goods yard; 3 Goods Shed; 4 Arrival platform with loco release; 5 Arrival platform with loco release, 6 runround road and /or storage; 7 Departure platform (arrival with loco release if required); 8 Departure platform; 9 Carriage siding with & Motorail loading/unloading; 10 Fish loading; 11 Milk loading.

The intermediate station has Goods yard, Goods shed and Milk loading facilities.

The rural terminus is a sleepy affair with a three coach platform with  loco release, a Goods yard and a Goods shed.  It was once an intermediate station on a longer branch but the line was truncated here and so the station is now the end of the line.
