Stopped at one of the 2 LHS’ near me yesterday. It was the first time in a few years for this one as I usually stop at the other one in the area which is far better stocked and exclusively trains. I got to see for the first time their new addition to the shop- a layout. Looks to be at least 4x8 or slightly bigger ( I didn’t ask) and they have 3 different loops of different scales. Lionel, HO and N with HO being the middle loop. On it was the PC heritage unit with sound and about a half dozen cars and a B&M caboose. I was amazed how a big unit can take the small curves as well as it did. Has to be 18” radius. Any other big locos made take smaller curves well?

Well 18" curves have been a defacto minimum standard for a long time, so most manufactures claim their locos handle 18" curves, but actual results may vary. I don't run on anything that tight, so can't say what works well on 18" curves. But it when it comes to switching out industries on the club layout, I have far less trouble with my 4 axle geeps than 6 axle locomotives or steam locos.

Depends on the brand too. A Bachmann will be made to take those curves where an Athearn Genesis probably will not.

Most manufacturers design the plastic or diecast articulated steam engines to go around 24" minimum radius. The large 4-8-4's and 2-10-2's will have a more difficult time than articulateds.
Most brass articulateds have details that will get in the way of the pivoting and are definitely not recommended for 24" radius operation.

Have HO Atlas ALCO & Athearn CF7 switchers. Modeling the Los Angeles Junction Ry which has a place with an 85 degree curve (ca 10"R). Laid down a 1/4 10"R curve & ran both switchers in both directions many timers with NO derailments!
