More Broken Locos, J72s

I think it looks like "LNER" is the common factor...
:-)

That's what I was thinking too. He needs some LMS loco's. ;-)

Actually I have a roughly similar numbers of LMS and LNER locos.
'Leander' is my sole working Mainline model.

The Mainline J72s were notorious for failing due to the plastic sleeve which holds each pair of wheels together splitting and allowing the wheels to revolve independently of each other and 'go out of quarter'. The BR Standard 4MT 4-6-0 also frequently suffered from the same problem with roughly the same level of frequency. Many years of experience with these suggests that lack of use, rather than over use, is likely to increase the likelihood of failure from this cause.
As the basic design of the wheelsets for both these locos doesn't appear to have changed significantly from the Mainline days, it's hardly surprising that the near-identical Bachmann examples also suffer from the same problem, albeit not to the same extent - although that may be because they've not been around for quite so long.
Another problem with some of the 4MTs (mainly Bachmann examples in this instance) is that the plastic driving wheel spokes (which are a force fit into the cast metal wheel) have a habit of distorting in shape, and can then catch on the valve gear or coupling rods and cause erratic running.
I think Bachmann are aware that the split chassis design is time-expired, and their plans to retool and rechassis the range of LMS 4-6-0 locos is perhaps a first step in doing away with this design. I hope they follow these plans with a similar retooling of their LNER range including the J72, J39, V1/3, B1 & V2 locos.

But will Hornby just let Bachmann bring out new versions of the complete set of 4-6-0's (inc rebuilt) without some sort of challenge. I thought they liked to have at least one medium express in their stable. Simon

They've got the Black 5, and besides they currently have their heads tucked neatly in their rectums churning out minority interest Southern Railway items.

Yes, I cant imagine SR locos selling too well after the initial wow! factor has subsided. Now, what we really want is a J6, K1, K2, L1, O1 O2 O4 2-8-0s, D16, B16....need I go on?

true, but the black 5 isnt a medium express passenger except as a standin - ignoring later BR when anything did anything. I'm sure I read somewhere that hornby's philosophy was that they tried to provide a complete range of steam engines types for all of the big 4. If Bachmann bring out the complete range of LMS 4-6-0's within a reasonable time period * will clean out almost everyones loco budget for a couple of years. Hornby cant rely on current Patriot retaining sales unless drop price to toy market. So what will they do ?

Nope, but can you start again with LMS, LNWR or Midland ? Simon

Surely there's a variation on the Bulleid Pacific that they have not yet modelled?
John.

Perhaps they could produce a Green LNER A4?
or perhaps a blue one that's not Mallard [Which anyone with any interest in the LNER will already have] ....
I can't imagine that sales of the wartime black model are particularly good, but then it was a hideous choice of prototype.....
WW2 was when it all went Pete Tong for the LNER...

My current total stands at 5 Duchesses and 4 Princesses but theres room for more of these beautiful models. Incidently its a well kept secret that Stanier and Bullied were in the pub one night and decided to swap designs for a laugh. Simon

You must have an awfully big layout to need so many Pacifics. My modest 20' x 11' (or thereabouts) OO-scale layout isn't big enough to justify locos which would normally haul 10+ coach trains, so I have to make do with 2-6-0 & 4-6-0 passenger locos, plus of course the inevitable 0-6-0 or 2-6-4 tank loco. Freight is a different matter and I've a couple of 2-8-0s and one of the new Bachmann 9Fs but that covers most of my loco roster.
John.

erm - its 5'*4' - OO. Next to my desk in t'study - where I work. I'm practicing till can annex the loft. Took 18 months to lay the track (4 times). Theres this colliery thats surrounded by a loop that the nearby shed use to give reparied engines a quick run to ensure theyre ok. All manner of stuff comes through - often light engine, but later on its suprising what was used for freight.
The pacifics are for the future layout but require a run now and again. Yes I can happilly sit and watch a duchess going round trainset curves for quite a long time. I am more than happy with my own reality, the 'tot' is happy with a mixture of PO wagons and coaches top and tailed by a 4MT and a rebuilt patriot.
Cheers, Simon

LOL - your railway mate, you run what you like - as you obviously do! ;-)

Simple... Have an engine shed scene like Model Rail keep banging on about ! Seen a few on the exhibition circuit, but they only tend to have 1 x 4-6-2 on the shed... Guess it is not a Sunday they model ! :-)

Modest 20' x 11'? Don't make us jealous John...

It will hopefully be going soon to be replaced by O-gauge in the garden! :-)

It's probably cheaper to buy a new Bachmann J72 than trying to re-chassis the older Mainline version, but if you prefer the other route then I've a feeling that Comet might have done a chassis kit for this loco.
