The #96 coal tower has a hand crank. I think it still uses a solenoid for dumping though.
I have the #346 manual Culvert Unloader with a hand crank. It is always a favorite.
There is a Lionel Coaling Station kit as well that unloads coal by pulling a tab. Reloading is via removing the roof and dumping coal in the top. The more modern version of this is the 6-12094 but I'm not sure this one operates at all. I cannot find the number of the older version. I saw a post (I think on this forum) at some point where someone incorporated a #96/97 coal tower elevator into this building. Very cool!
I was not aware of the #460 piggy back loader, I'll have to watch for one of those.
Kids (of all ages) like the hands on accessories!
