Powering a JLTRT 50

[Ressaldar]

Hi Guv,

I notice that on your trailing bogie that you have not fitted any pick-ups, is there a particular reason for this? I would have thought that by using Roxey steel wheelsets, you can ensure that pick-up problems are a thing of the past, especially when using JLTRT resin bogies with no insulating problems to overcome.

I have been test running and I just didn't bother fitting the pickups before painting. I don't find plungers too much of a problem so I may well use them.

I have a class 47 powered by 2 ABC gear sets and it's very powerfull it will tow more than it's real brother but again it depends on what you want to do with it if your railway it a shunty plank the running qualities are superb 1 should suffice but a roundy roundy with near prototypical length trains 2 would be better

?300+ for a couple of motor bogies is a tall order though Ian :shock:........if I motorise both bogies I will definitely go down the motor/gearbox route :scratch:

And if you're going to motorise a working fan - do it before you fit the sides to the roof! DOH! I've made the same mistake twice now

Sorry, rant over..... normal service is now resumed.

yes I agree but as I only paid that for the whole loco it was a bargain too good to miss

Was the seller aware of what he was giving away..?!?! :lol: :lol: :lol:

So, here's the ABC Motor bogie (remember this is a Class 37 bogie although the ABC Class 50 bogie is only slightly different and has the same key dimensions) in situ under the JLTRT Class 50 chassis. The cut-away takes you fairly close to the bogie centre, but still plenty of strength there, and no need to further weaken the chassis frame at each side. No problem at all

 

[D1054]

A little more progress with the non-powered bogie being wheeled over Slater's pickups, and the pivot solderedup andin place. Body mounted, but needs a little attention as the ABC bogie rides very slightly higher than the JLTRT bogie. I doubt many will notice the ABC bogie was originally for a Class 37 - but there'll always be one or two that do!

Hi D1054,

those ABC bogies certainly look good. I have a very soft spot for the ABC range and have just had an offer accepted for four traction motors fitted with 3'9" wheels - so I have the choice of Class 24/25/35/40/45/46/47/56 and then do I put two in one bogie and therefore be able to do two locos or all four in one loco. Whatever I choose, it will meam a lot of surgery on a JLTRT chassis block to clear the way for the gears which are behind the wheels and also bear in mind that they are outside bearings so the axle boxes will need drilling out as well as thinking about making the outer frames removable for maintenence purposes.

Any thoughts would be welcome.

regards

Mike

Mike quoted "...four traction motors fitted with 3'9" wheels...."

And "......a lot of surgery on a JLTRT chassis block to clear the way for the gears which are behind the wheels and also bear in mind that they are outside bearings so the axle boxes will need drilling out as well as thinking about making the outer frames removable for maintenence purposes."

Hi Mike, I'm not the best qualified to answer this for you as I've steered clear of the traction motors for exactly the challenges you will have to face with the bogie alterations. Please bear in mind that I'm quite new to this, and my Western, 25, 37, 40 and now the 50 are my first model locos in O gauge (I did do some R/C Gliders OO and P4 modelling before though ).

I think that I'd be tempted to design and build a completely new bogie in brass (for either one or two traction motors in each) rather than attempt the surgery required on the resin cast bogies provided by JLTRT, but it should be reasonably straightforward to do on AutoCAD or TurboCAD or similar. Now you've raised it, I quite fancy having a go at this now I've had some, albeit limited, experience :scratch:

I'll have a look at the ABC website and see if they post a diagram & measurements for the traction motors - if they're there I'll have a go at mocking up a bogie design for a Bo-Bo and 1Co-Co1 - Unless anyone else out there knows these are already available? :wave: I'm off on holiday for 2 weeks tomorrow, but the laptop will be coming along; and I'll need something to fill those sultry summer evenings.....

All the best, Ian.

Hi Ian,

many thanks for your quick response and perhaps it will be best if I start a new thread rather than hi-jack this one, so I'll hop over to that with my reply.

By way of an update I've taken the plunge today and placed an order with ABC Gears
for a pair of their motor bogies - Gulp! Better not go to Telford then

Thanks for all the info provided. Helped greatly in making a decision.

:shock: no shortage of power then :laugh: still at least you know it will do all that is asked of it, there's nothing worse than a model in which you have no confidence.

Well I do have half a plan forming to build up the two ABC bogies and two unpowered JLTRT dummy bogies. I have some spare sets of wheels to enable me to do this. That way I can try a twin powered loco and a single powered one to see what suits better. If I decide a single powered bogie is enough I then have another set ready for the next 50! (of course they'll be another one someday!)

Thats always a problem, you start with one, then its another, and another :laugh:
