What was wrong with the other switch stand? I can see some visual alignment confusion with this one...


We 'could' move the attachment point for the throw rod above the pivot.
But that would mean the stand puts a vertical force vector on the throw rod since the attachment point is offset from the plane of the rails.
Maybe add an extra lever in the middle to reverse the motion? This also has the advantage of cancelling thermal expansion in the rods.

I got more...   ;)

First train of the day.













Last train of the day.



Dana ran 10 to the end of the siding for a photo op. Number 10 is as far north as you can go and 10's tank truck is sitting on a piece of original WW&FRy rail that was found while clearing at T.O.M

Thanks for the post B. 

Nice photo essay of the first run around move at TOM for those of us who missed it.

I have got to say, the whole time grading up there last year, I had this very picture in my head. So glad it has come together so well.

TOM Extension turned out tops. Well done.
Extensive gallery of construction pics posted on NGDF was super impressive.
Suggestion--with a light fence post and a 2'x2' square of plywood?, make an official EOT red board to set between the rails, have a ceremony when it is advanced to the latest mainline end.

I thought the plan was to have the train set off in the siding where it is relatively level - and no chance of rolling downhill - instead of tying up on the mainline and having the locomotive run around the train by using the siding?

Where the train is left on either track, forms a bowl towards the South switch, heading towards Alna Center. The main line has about a 3 car level spot, and then at the frog at the Main line stub, the grade begins to descend north.

We thought it best to leave the train on the main line, in case a train is having trouble on the downhill they have some level ground to regain control.  If they don't then the mainline switch is lined for the siding, and the spur/siding switch is aligned for the spur so that there's extra room to stop the train.

Time to break out my "Top of the Mountain" T shirt!  This was an important date in WW&F history - well done!
And thanks for sharing the photos.
