Got fed up with trying to stop kit built lnwr cauliflower from derailing on curve (2nd radius). Perhaps should have used a slimmer motor and driven of rear wheels cos centre drivers have no lateral movement at all. Anyway filed centre drivers to be flangeless - is this a crime. Doesnt derail anymore.

2nd radius curves is a misdemeanour, I refuse to hear the other... la la la ...

What's "2nd radius"? I couldn't find a reference to that in the 1927 Railway Design Manual. Must be a new-fangled thing - I bet it uses FB rail as well :-)
As to the rest, I'm with Greg...

Second radius is a model railway thing, not a prototype railway thing.
In OO it is 438mm or, if you prefer, 17¼ inches.
'curves is a misdemeanour' from a rivet counter ? Let he who is without sin ....

Methinks Paul was kidding...

Second radius is ok for train sets, not for a model railway (VBG) use! ;-)

It's not a crime in the eyes of God provided it's a Crewe-designed locomotive :o)

I thought that only applied to Swindon?
Perfectly OK for most (all?) LNWR 8 coupled locos.

The Cauliflower is an 0-6-0
An 0-8-0 wouldn't have a centre axle.

Yes I know that, just introducing a bit of humour ;-)
Like most of the other replies, trying to get models around 2nd radius curves (bends ;-) ), is rather expecting a bit much. But hey, its the OP layout, not mine.

A lot of American 4-6-0s built for secondary railroads had flangeless centre drivers. These were also wider than the others:
Nail on two more wheels (one each side for prefernce).

I only count rivets when I'm installing them and I do have a visible circa "2nd radius curve" on my layout. (I can defend my use of that abobination if required) I also have three 2-12-0s and several 0-6-0s with _all_ flanges on the wheels!

What else do I do in 00 on a 6*4 practise board. Could either have a fiddle yard with 2" out and back or a set of ovals. Have you ever tried running in a new loco on a shunting layout ? Before it reaches scale 100mph its crashed.
Cheers, Simon
Thanks for the inspiration - just compared wheel spacing with a hornby Jinty and theyre identical. Obviously should put traction tyres on the centre drivers !
Cheers, Simon
well it was FB before I laid it.
CHeers, Simon
Rubber wheels would be even better!

Knock a wall down! At the design stage of my layout I had to make the decision whether to go around the walls of my 17' x 12' room (also computer room and workshop) or build a table style layout against one wall. The fact that I'm sometimes in a wheelchair sort of eliminates the advantages of a "walk around" layout so I went for the compact 16' x 4'6" table. It's
2'6" wide in the center woth "dogbone" ends. At one end the return curve is visible as you can have just so many tunnels before it becomes unbelievable. The visible curve has only 4' width to get around 180 degrees so it is a transition curve from about 6' radius tightening to 18" for about 45 degrees at the center. A low bluff and trees block the view at the tightest point. It's not ideal but looks reasonable and most of the baseboard can be reached one way or another.Regards, Greg.P.
