MTH Premier AC-6 cab forward, overhang on 072 curves

I'd like to know if any part of the Premier AC6 cab forward sticks out more than about 2.5" from the rail head on 072 curves. Can anyone check?

I agree that it would be useful to have a database of this type of knowledge, perhaps built into layout design programs like SCARM.  I'm in the process of designing a layout, and find myself asking the same types of questions.  Unfortunately I don't have an AC6, or any articulateds, for that matter.  Sectional track has un-eased circular curves.  Unless the rear engine also swivels (RailKing-style), this makes for some pretty extreme overhang!

Lou,

Here is the best picture I could get - this is an older Premier PS1 AC-6 on O-72 track.

It looks to be just over 1.5" on the overhang.  I hope this helps.

Thanks. That's from the rail head correct? I assume that the rear hangs out more than the cab, as that's where the articulation is. Looks like the overhang isn't much worse than my Premier ATSF 2-10-4, so it should clear things fine.

A database with locomotive overhang on their minimum rated curve would be helpful. We all end up buying stuff after building a layout. It would be nice to know if things will clear before purchase.

Technically, it was from the side of the front driver, which was even with the edge of the rail.  🙂

OVERHANG IS HS!

Trains run for the most part on straightaways; not curves. Curves are the exception.

Yes I know about the  famous horseshoe curve but again that's only a small small part of the overall running line that for the most part is straight.

This only becomes an issue because of our layouts that need curves to come back to the starting points. Our layouts are vastly small compared to a real line so seeing an overhang on an 072 track seems Large by comparison.

And I don't care I run my 21" passenger cars anyway!!  so there!

Not sure how the last post before me is helping, but let me try.

I have an MTH Premier AC-6 Cab Forward, on Atlas track 072 curves. I measured 2 3/8 inch from the center rail for the rear. The cab is not hanging as much.

Hope it helps.

Thanks. That's helpful. I figured the rear would hang out the most vs. the cab. I'll check for clearances using the measurements you and C&O Allie (Allan) provided.

It's on the same plane so it's fine. Thanks.
