They WILL go round- a tale of two TT carriages...

Having been invited to an Agricultural Show and to bring TT & Friends, I had to get them off the shelves and make them presentable. The two coaches were put behind Thomas (who had just been treated to a wash and brush up. Usual problem with R1 curves!

So, having used chains, altered couplings, etc, they just proved that R1s were not for them! However, as they are an integral part of the TT entourage, something had to be done - and pretty sharpish too!

As we are all aware, it is the extremely long wheelbase that causes the problem.

There are prototypes for unreasonably long wheelbases on railed vehicles but I won't bore you with the deatails. My thoughts were , using some freight trucks, they would become bogie coaches and they WOULD go round the curves!

Just testing for height....

and one of the freight trucks out of hiding..Time to take these two in tow! (4).JPG

To save messing about too much (as I was short of time), I decided that I would use the knuckle couplings to join the two coaches, and hook and loop to top and tail the pair.

Not being of the Conan (the Destroyer) type, I opted to remove the bodies and make replacement bases to mount the trucks on. I did think of wood and then I remembered some pieces of uPVC facia I had removed from the house. Using the circular saw, I cut two pieces to size.

I used the original parts as a template to drill the holes in the replacements, did a test fit, and then removed for a quick overspray with some automotive matt black. Once dry, the two bases were screwed in place using wood screws (I reckoned that the uPVC wasn't up to having the holes recessed like the originals) so I needed some longer screws.

The odd holes were fixing holes from a previous existence and will not be seen as the long as the coaches do not fall over!

The two original bases had their screws taped to them and were put to one side (in case they ever needed to be refitted).

Then I needed some foot boards. I thought I had some bass wood strips - I had, but they weren't the right size! I found some offcuts of hardwood and made them fit - using Gorrila Glue and brass pins.

The wood partially covered the screw heads and I should have spray painted the foot boards before fitting! However as it was now evening, I thought I'd touch them up in-situ. H'mmm

I made a couple of uPVC blocks to mount the trucks on each coach - using M8 washers to facilitate pivoting.

I found that I didn't have the right type of black paint to brush on (I could have sprayed some into a lid to brush on but I thought it might dry up before I completed the task.

The result of using some black rust-proofing paint turned out to be rather a coagulated mess - plus the glue (brown when first applied) turned white and was rather averse to receiving a coat of paint!

As the paint was still tacky (by nature and in appearance), I gingerly fixed on the trucks, I had to alter the rear coupling on Thomas by using one of the supplied lowering adaptors but I left the front one in case TT should do a cab forward dragging the Troublesome Trucks!

A high speed run in the garden proved that all was well so far. It was then that I returned them to the shed to dry overnight.

This morning, with the paint still not fully cured, I tested them in the trailer...

Again, I let TT run away at full speed - no problems now on curves (reverse or otherwise!).

I could, but probably will not, make up some buffers, hooks etc - instead leave well enough alone! The height is the same as they were originally built, plenty of unprototypical space between each one, and they'll stay like that until I stop using the trailer!
 
Ace job, and it will still make the kiddies smile, they won't check the engineering.

Yes, that says it all - great work by you, great fun for the kids and something for the rivet counters to complain about - so everyone's happy. (Well, I suppose the rivet counters may be after a fashion.)

The rivet counter can go and get the original books out (No 4 Tank engine Thomas again) and see that the illustrations by C. Reginald Dalby Annie and Clarabel are indeed bogie coaches, so well done Trammayo, 2 smart looking coaches....we're coming along, we're coming along. just make sure they don't lose their nice guard!!
Happy read for me as a child and my son. :)
 
As Fezwig says the original coaches shown in the books were bogies, so we'll done.

Another alternative that involves slightly less work is to mount swivel LGB type couplings ( I made some from Playmobil single axle bogies).

To be fair to Annie and Clarabel their wheelbase is actually rather short and they run well compared to the Emily/Christmas Coach which binds badly and suffers the same coupling issues.

I still say it is a pity Bachmann never considered these issues when designing the range.

Well done again and thanks for posting the very clear images.

Drat - I'd forgotten about my Emily coach (still boxed). Maybe convert that to a true Cleminson system?
 
That would be good, but if you did the same again it would be brilliant and probably easier. They use the same body as A&C.

The two rigid outer axles each present a ridiculous angle to R1 curves and they make a horrible squealing sound as they go round them.

Irony of course is that the 6 wheel Xmas coach is sold in the Xmas set that contains R1s!

Or some smartypants trying to ruin your Chr*stm*s (nearly typed th 'C' word) :mad:

Ah, I was referring to the missing buffers and other detail items. I must look more closely at my Thomas reprint. (I didn't even know what bogies - well, the railway sort - were when I was reading my original first editions.)

Yes, at that time of life I was aware of two different types of bogie - the bogey man (coming to get you if you didn't go to sleep) and the other was sometimes in the plural.....
 
You could have turned the two fixed axles into swiveling axles, and put a third axle in between them, linked it to the inside ends of the swiveling axles, and put it into a slot underneath the centre of the coach (but at right angles to the length of the vehicle)) and you would have had a 3-axle coach! Simples!
 
Great job Mick,I think they look better with trucks anyway;);).

Almost, but not quite, the Cleminson system. For me, it was a relatively quick fix without destroying the original wheeled underframes.

The Thomas locos (at 12 volt) go like a rocket - and the bogies worked extremely well around the numerous R1s and reverse curves. I do control the speed in case anyone points this out!
However, for me, the TT stuff will probably wait another year before they operate in my trailer - if ever again (they might appear in the garden sometime though!).

Good job there now I can follow you and do the same mod as most of my curves are R1
