New to me 48 tinplate transformer house,

Two wires in=AC three wires out = one common and two posts of different voltages? Homemade job. Plug it in and stand back! If it and you survive, test the posts with meter.🤪

Seriously, it's a whistle shed that sure looks like someone adapted. There's no rehostat which suggests fixed voltage outputs. If you decide to test it, be aware it might fry. If you can get it out, and test outside would be wise. Or perhaps come up with a modern application. My two cents...

Your photos were bugging me so here ya go, terminal on the right is common. Then 6 volt in the middle followed by 8 volt on the end. I can't recall the accessory # . Hope it helps

I believe those sheds came 3 ways:

1) nothing inside

2) whistle inside

3) transformer inside

I know that at least options 2 and 3 are correct, not truly sure it came with nothing inside.

I don't have a picture of the bottom, but it was definitely purpose made, not custom.  the transformer is held in place with tab and slot construction.  No way that's a home made job. I just don't know much about it.

Right, the photo I posted is of an original in my collection. Did some serious digging to find it. No # on it. Lionel cataloged a #1560 in 1933 to go with Ives mechanical sets. No transformer or whistle. In 1934 catalog Lionel Jr. Rheostat version # is 1027. Winner Lines transformer without rheostat is cataloged as #1012 per three binding posts. Winner Lines #1017 Deluxe transformer has a rheostat. Now, what actually made it to production? Maybe Rob English knows...

Ugh.  Many varieties, tons of colors.   Lionel and Ives used em.  48W  1937-1942  1012 (Winnertown or station) trans inside, 3 binding posts.   1932ish 1027, 1028, 1029 (Station or nothing) Lionel Jr line trans inside , 2 binding posts, 1 control handle. 1933-1937  1560 Station for mechanical trains, nothing inside

JHZ..yours is a 1012... posts are common, GV (i do not know what this means) and 7.5 v. I dont know order.

I've got the old whistle house in amazingly good condition. It was one of those proverbial finds in a cardboard box that a guy gave me.

Still works great.

I vaguely remember my Dad having one of those whistle sheds. I think I burned out the motor one year from using it so much.

This is why I don't delve in electric trains (lol) Cool litho though!!

Rob, thanks a bunch for the id help!!  I will probably put a sticker on the bottom or inside to remember.
