?Tightest continious curve?

…I just happened to remember we have a very tight curve on the NS here in Muncie. I don’t have the figures but it’s location is the transition from the NewCastle line to the Frankfort line. For anyone caring to take a look via satellite or in written specs, etc…I’m referring to the curve off the NewCastle line into Muncie from the south and curving to the west to go across {Diamonds at CSX}, to direct it to the Frankfort line…{northwest}.

I’d be interested to find out just what those curvature figures really are.

I don’t have such data.

That curve may not be as bad as you think. The ETT lists a 25mph restriction from MP CF 119.8 (6th St Interlocking) to MP CF 123.2 (North of BATH interlocking).

The same timetable lists a 15mph restriction from MP CF119.8 (6th St again) to MP SP 174.3 on the Frankfort District Connection Track going West.

It doesn’t give degree or radius, but it would appear the through route for New Castle District trains isn’t as sharp as the route trains to/from Frankfort have to take to/from Cincinatti.

There’s a pretty sharp curve on the old Erie in Hancock, NY. Between that, the old truss bridge, and a half dozen crossings in a half mile, they pretty much crawl through there. I know a couple of people who don’t appreciate the squealing after a night of imbibing…

274 FT is a tad over 21 degrees of curvature (21d-01’-43"; 100ft is a 60 degree curve))

It’s one thing if its just the locomotive in the curve, quite another if it’s coupled to another locomotive or car (then coupler swing and drawbar forces come into play)

If you mean this one http://tinyurl.com/5nbjos it looks to be no sharper than 12 degrees-- likely 10.

…Mike, yes that curve on the connection and then crossing of the diamond to get across CSX is the location I spoke of. 15 mph is rather slow…I know, looking at it from ground level it sure made me take notice…It passes rather close to some buildings there.

…With a 15 mph restriction around that area It has some meaning of curvature. It certainly does take one’s attention looking at it from ground level.

That Google map photo of that area…has the Cardinal Greenway marked incorrectly. If one starts at the {reddish roof depot…clay tile, just to the left of Broadway}, and follows the trail north from there for the next half mile or so it is marked wrong. Actually the trail is to the left of where it is marked.

Tree, I know where you mean, but I’ve never read about the curve there being too bad. Either way there aren’t enough trains there anymore to bother anyone!
