All the talk about the forthcoming Vision Big Boy made me nostalgic to run my JLC Big Boy. People speculate that the new Big Boy will use "the old tooling" and that will be fine with me: the JLC is just a splendid loco, very detailed and quite handsome.  And it has quite good sound despite its age, great pull and wonderful slow speed control.  I've already asked my LHS to order me the new one,  but this puppy is a very fine loco in its own right, despite is approaching obsolescence . . . 

-->When I looked at the log card  was surprised to see it had been a year and a half since I had run it: scale articulated locos will run on my layout - I laid out and tested clearances when I built my "big loop" with this very locomotive on the track to test each section I built, just to make sure - but their three-inch front stick out on 72" and 84" curves looks silly, so I seldom run them.  In fact, I've encroached the track with buildings and trees:  I had to remove two buildings and fourteen trees to get the clearance for this puppy's boiler to run today.  Here is is, freshly lubed and checked and pulling 39 PFE and SF reefers with a caboose.  My big loop comes out of "the mountains" and loops around behind main-street and back down through a tunnel and under itself before heading off for "the plains" -- this train is long enough that I can actually get the loco and caboose in one photo (#3).

Lee, Could you post a couple of photos of it on a O72 curve please?  I'm saving up to get the new Big Boy.  I was planning on using FasTrack O48 and O60 on the layout I build, but I think I can shoehorn O72.  Main problem being I have to clear a door to the outside world.  My boys will want to play in the back yard I'm sure.  But I need to know exactly how much clearance from the center rail I need to the wall.  Right now I have it at 3-1/8" since that is what my K-Line baby Big Boy needed for O36 (Figured if it'd clear the wall with a tighter curve, then it'll be fine on a bigger curve.).  It'll be an around the room layout so when the BB makes a turn to follow the walls, I want to make sure it doesn't hit the walls.

Here it is on O-72, and it needs it: mine will run on nothing tighter.  Whenyou install your track make sure you have three and one half inches of clearance on the outside of curves, minimum - more if you can. This puppy will take it all.

Lee:

Looking good, Our Big Boys will pull a ton of cars.

I don't have a scale one yet, Didn't have the curves for it.

But my Imperial RK Big Boy has pulled 58 cars & the only reason it didn't pull more was the lack of track to put them on.

And yes, mine looks like that on O-48 or tighter but the cab swings even more !

My K-Line has more swing on the Cab side too.  The front of the boiler hardly swings.

 

Lee, thanks for the photos.  That is quite the swing.  Is that 3-1/2" from the outside rail, or the outside edge of the FasTrack base?  That is a lot for sure.  Not enough to keep me from getting one, but enough I might not be able to fit the track in the space I have.  I may need to do a dedicated around the ceiling loop just for this fine lady.  I might just have to wait until I have it in my hot little hands to do some measurements to get an exact min distance, which isn't all that bad because I'm sure I won't even get any track to lay until end of next year, later if I buy one of these.
