ElectraRail Tribometer Train
« on: May 09, 2020, 02:30:47 PM »
I have fondness for engineering trains so last year I bought a Class 24 ďExperimentĒ thinking to make a Tribometer train.  Rather than just buy the standard Farish parts which are expensive I thought to use the vinyl overlays from ElectraRail graphics which I bought earlier this year.
Some questions have occurred to me and I thought sharing the build and the experience of using the overlays. Perhaps other who have completed the vinylís might care to add any useful tips I know I would have liked some guidance

What would the interior of the coaches look like?  I guess desks, workbench and equipment racks but would part of the train be accommodation as in other engineering trains?

What would be best for weathering the coaches?   I would like them to match the engine as far as possible.  The van is going to need a lot of weathering to tone down the red

There are no ends provided for the coaches except for the driving car so I presume that the coach ends are left black.  The Farish ones continue the colour scheme round the end but looking round at pictures of the real thing  there seem to be a mix of black, blue, yellow and black and the side colours  Does this means anything is possible?  In the end I have left the corridor black/grey and used a bit of Royal Blue over the black at the edges.  It does not match the side blue colour but it suggests blue.

Hi there,

As it happens I've just been doing this one for someone else.

Loads of info out there, not all in the public realm though.

Some links to help:-

Browse this site to find more photos.

A couple of write ups on doing this train in 4mm were in the DEMU magazine some time ago.

Reference to the UPDate index gives one in UPDate7 (Compendium 2) and one in U50.

If you are a member they are available in the online back issues section of the DEMU Wiki

Thanks
Phil H

Making the Tribometer Train with the Electra Graphics vinyls is a fun pocket-money project. You need two Mk1 coaches and one VBA box van. I'd suggest getting the old Mk1 coaches (which you can pick up for a few quid at any model railway show) rather than the Blue Riband ones. Likewise VBA vans are usually kicking about cheap enough in the secondhand trade ó I think I got mine from Hattons for a fiver.

Stripping the coaches back to the transparent plastic is a bit alarming but not hard. I think I used nail varnish remover and a toothbrush. It wasn't difficult to do. I didn't strip the van but I did put a coat of primer on. Once everything is dry, you apply the vinyls. I did the smaller vinyls on the van first to get the hang of it. Then painted back whatever needed to be done (mostly the ends of the coaches and anywhere the white edges of the vinyls showed through) but otherwise this was an easy project that didn't need any specialist tools.

The end result is as you'd expect for vinyls. The colours are rich and the printing is sharp, but the vehicles do look a bit 'flat' compared to coaches or wagons with separately fitted detailing parts. A spot of weathering helps, and I suppose you could go the extra mile and add detailing parts yourself. The VBA van for example actually needs corridor connections, which could be salvaged from an unwanted or damaged coach picked up at a model show or made up from plasticard. Multiple unit jumpers could also be added to the Auto Trailer using bits of wire and blobs of plastic. All sorts of possibilities, really!

I really enjoyed using vinyls, and they are a very cheap and quite easy way to build unusual rolling stock. Invicta Rail do actually sell a limited edition VBA van now, but the other two vehicles in the train are, I believe, not produced as RTR models.

Cheers, NeMo

The VBA Van
I thought I would start with the VBA Van as it looked the easiest!
The VBA van has a lot of raised details on the sides.  I sanded these flat with fine wet and dry.  The corners of the van have a small indent in them and I did not think the vinyl would fold into them.  I decided to sand the sides at each corner with a gentle curve to remove this indent.  This seems to have worked but I think that filling the ends and squaring the corners might be better.  The indents in the longer sides donít cause a problem and donít need to be filled.
The underlying colour of the plastic is white and I left the body as white which was a mistake.  The final colour of the vinyl depends very much on the colour of the underlying plastic which for the coaches is transparent.  With a white plastic the vinyl to very red see photo. 
The vinyl finished with a very small white line showing top and bottom.  A touch with a black pen or paint sorted this but spraying the body first would have been better
Points for the VBA Van
1.   The corners need to be squared up or sanded down
2.   The raised details needs to sanded smooth
3.   The body should be sprayed black or dark grey?

Did you weather yours?  My engine is weathered and as you can see by VBA van is very bright mainly i think due to the white palstic underlying body

Good point about the VBA ends the vinyls have printed doorways but ideally ones could be added

Did you weather yours?

I just went and checked -- yes and no! The roofs and underframes were already weathered from another project (I'd used the salt crystals method to 'age' the roof of the Mk1 coaches while they were still in BR blue livery). But the vinyls are as they come from Electra.

I should probably weather them, but evidently never got around to it! I have the original Modelzone 97201 that isn't weathered, so leaving the vinyls in pristine condition must have made sense to me when I did the conversions. As you say, the current Farish version of 97201 is rather nicely weathered, and I think you'd probably want to dirty-up your Trib Train to match!

The Coaches


The two coaches I had were Farish MK 1 coaches.  These were marked Made in China and seemed the same vintage all regional railways.  Electra recommend BSK.  I had one and a Second SO.
The BSK had no surface detail at all which made life much easier.  The second had moulded door handles and hinges which had to be sanded off and the plastic polished
The BSK had no interior but the SO had an interior which had to be removed and unfortunately it was glued in and removing this caused some damage which proved impossible to completely remove
Both coaches had a blob of paint on the inside blanking out a window, these blobs did not generally match any covered area on the vinylís and so had to be removed.  No stripper I had touched them so I had to sand them off
Stripping the paint was fairly easy better the last ones I did which were marked Poole made.  I used cheap nail varnish remover consisting mainly of acetone.  The plastic seemed to be slightly cloudy perhaps age?  I used cotton pads to apply the acetone and I wonder if these dulled the surface certainly around the old windows there was some dulling and misting.
 So we have to polish the plastic up again.  After a net tip I started using toothpaste and this certainly was a good start.  In the end I used some Poundland nail polishers which had a variety of finer finishes and the ďshineĒ one seems to do the job but be prepared for some hard work especially if you have had the sand any areas.
Test fit the vinyl before applying.  Sometimes then are a little too bit large sometimes just right.  This is especially important on vinyl like the tribo train which have straight lines and detail close to the edge which could be lost if matching at the opposite end.
It is possible to peel back the vinyl if you have a problem but be careful not stretch the vinyl.  Check carefully for any trapped material under the vinyl.
You may need to trim back any overhanging vinyl at the edges.  The glue is strong and apparently grips better with time but if any edge lifts then a small application of super glue should fix it.
A coat of ant-shine spray will take the shine of the vinyl but donít forget to mask the windows

1.   Try to get a MK1 coach without any raised fittings
2.   Use the minimum amount of paint stripper
3.   Polish off any dullness or misting
4.   Test fit the vinylís before applying
5.   No lumps or bumps the smallest particle will show under the vinyl

No more work for the moment as i am waiting for a new can of anti-shine varnish which has seemed like gold dust online

Thansk to ScottishModeller for the links most interesting but nothings much about the interiors i think i shall just have to be creative with what interiors i have

Indeed. If I could be bothered, removing some of the seats and replacing them with black-painted vertical rectangular blocks to simulate recording devices and computers would seem about right. But since these coaches don't really reward close-up viewing, and are best seen while moving about as unusual additions to the normal roster train operations, I'm not sure it's worthwhile.

But then again, I'm nothing if not slap-dash when it comes to railway modelling!  :D

Nothing slap dash about your models

I agree but one caoch has no interior so i am cutting up some other interiors to bodge something for both coachs
