thanks a lot for all these interesting remarks .
For the people in shirtsleeve I have two remarks : in some cases it's normal, in march/april the temparture become warmer (all is relative !), the canadian are braves and for the people who works in the building at the 1st stair where the evaporator is located (with wooden strove), it's very hot and there is a lot of vapor. It's not a sauna but very nearly. For the other people (on the critters) it's a mistake
but I also runs these critters on others layouts . It's the reason why.
In theory during the maple sugar season (in march , april in canada) there is still melted snow. According my old souvenirs from the only times in went in canada and according the photos of tourists taking during this period. But If you told me that it's unreal, excuse me for the mistake. I have to correct it. It's not so easy to try to recrate a piece of canada from france.
for the sap buckets or taps, I have to create it, it's a very good idea.
I have not already show the wagons because I need to paint it.
