As may be apparent, the sharpness of the service track curve and the clearance of the service track to the southeast corner of the enginehouse were two of three pinch points which we had to optimize.  The third pinch point was the clearance between the northwest corner(s) of the enginehouse to the southeast corner of the car barn.  We wanted to keep that pinch point as wide as possible to permit the passage of emergency vehicles with a safe margin.

The variable was the rotational position of the enginehouse- rotating it east gives more room to the car barn but makes for a sharper service track curve and tighter clearance at the se enginehouse corner.  Swinging it west does the opposite.

I’ll see if I can send a map of our actual CAD layout to Ed as an image or pdf for Ed to post.

Thanks,
Jason

The centerline of the service track clears the corner of the engine house by 5’, providing a 10’ loading gauge window.  This is the same as the width of the shop doors, and the new doors into stall 1 of the enginehouse.

The service track required a 25 degree curve for the layout to work.  The 25 degree curve will be constructed to 24-1/2” gauge.  Doing so should allow access by all equipment- however this will be carefully and directly confirmed after construction.  Recall that that historically the sharpest main line curve on the WW&F was 20 degrees- we are quite certain there were sharper yard track curves (such as the one just north of the shop in Wiscasset).

The intent is that the service track (all the way to barn 1 switch) be kept clear of parked equipment so it is available for servicing locomotives and accessing the north yard (and the turntable from the north yard).  As a norm, trains or equipment shouldn’t be parked so as to block this usage- though I’m sure we’ll have some exceptions based on circumstance.

Thanks,
Jason

I was getting this a while back, but now http redirects to https automatically.

Which are you seeing in the address?

not sure that the Bridgeton plow could even make it to the service track

The turntable lead (from the south yard) and the run-through track (from the north yard through the engine house) can both accommodate large pieces of rolling stock.

The photo is a little deceiving. The only thing that may not clear is the Bridgton plow..

Just checking: lately I have been getting a 'not secure' indication on the address bar of the discussion forum.  Is this in any way related to the new web page?

Thanks

Perhaps anything too big to get on the turntable can't get past the engine house; think of the engine house clearance as a filter.....

If I understand it correctly, the issue with the bypass track is not proximity to the engine house, but the angle of the curve around  it. There may be restrictions on what equipment can use the bypass track (no coaches, for example.)
