Congrats are due

In the modified words of Hannibal Hayes from the A Team. 'I love it when a plan starts to come together"

Keep up the good work. It will be an impressive viaduct when it is done 

Very nice work

This really seems to capture the look of the prototype.  Nice work!

I found this photo by Liz on Flickr.  Was the water lower in your era?

Water Levels

I am targeting 1958 for my layout. At the viaduct, water levels have probably been close to this for a long time. In a historic map of Napanee that I found online frrom 1878, the viaduct was single track. Amusingly, the stonework visible on the picture you found is probably the original. When the viaduct was double tracked, the piers and arches were expanded to the northeast by folks with enough pride and craftsmanship to follow the style of the original. If you look closely at the piers the line is just visible. Under the arches it is all a concrete shell -- the actual arch on the other side is made with much larger stones.

Out of sight in this picture is a dam. In the 1880s this diverted water into a mill race that appears to have driven a number of businesses. Traces of this diversion are still visible -- although the dam itself appears to have been upgraded. The cascade downstream I have tried to model in compressed form in my layout.
