Title: Full HOBC Train (well a few wagons shorter)
Post by: Snowwolflair on May 07, 2018, 12:44:55 am


I just loved this video of a HOBC train (High Output Ballast Cleaner) when I first saw it and whilst there are no N locos, even as a pair, capable of pulling a full train, as most of the wagons are available as 3D prints I decided some time ago I wanted to model it.  The HOBC is available from Modern Image Models as 3D prints and the MFS-100 are available on Shapeways from the Hubert shop. The train will also have a VM80/NR, that's added on occasions, which is a vacuum unit to excavate ballast around points and junctions and this is also available from Modern Image Models.

I will probably have to hand make the PW-RT and NPW-RT power pack cars as no prints are available but these will be straight forward if I can source drawings and the container flat should be straight forward.  This will be a long project but tonight I made a start, and along with this can I express my thanks to Hubert for scaling his 1:160 prints to 1:148 for me.

Good grief! :goggleeyes:
That's one helluva length train and says something about the tractive power of a 'Shed'.
Glad you explained what HOBC means, though, as I wouldn't have had a clue :dunce:

This video shows one in action.  Sorry the text is in German but basically it lifts all the ballast under the track separates the big pieces from the debris and returns the good ballast back to the track.  It then tops it up with fresh ballast from the wagons behind and passes the waste ballast forward to empty wagons.

Wow...
That is going to be one impressive train.

The first video posted shows the HOBC train from Northallerton, so naturally my interest was poked. The video says the train is 2500 + feet long, that is 5 metre long train in N gauge. Given that our layout, Northallerton (see sig) is 7.5m long, in theory we could have this train running on Northalerton and its entire length be on view. It would certainly show up the compromises we made when building the layout. Unfortunately our layout uses a multiple fiddle yard system where the longest train we can accomodate is only half the length of the layout, so about 3 metres in length. still pretty long though. Im well tempted to have a look at this as a possiblity. Having said that, its taken me about three years to build and finish off the track tamper from Moden Image Models.
@Snowwolflair (http://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=3761) do you have any idea what the finished length will be?
I'll be watching this with interest.

cheers

IIRC it's symmetrical (with the MIM bit in the middle, cabs facing inward), so you just need to remove a few of the MFS wagons from each end and it can still be prototypical.

Certianly watching this with interest, at £157 for half the 'unit' plus £45 for the decals/wheels/glazing etc and £100 for each pair of MFSs it's far too rich for my blood!

Just over £2000 for a full length set by my quick calculations. Plus a pair of 66s. Eek.

My plan is to have a train configured as follows.

Loco
VM80
MFS100 x5
NPW-RT
HOBC
PW-RT
MFS100 x5
Support wagon
Loco

So about 10ft, primarily because two locos will struggle with more than 45 bogies worth of wagons.

Its an eating elephants problem, i have been buying the bits a wagon at a time over the last six years. however the PW-RT and NPW-RT don't exist yet.

I have been assembling the articulated bogies.  A fiddly task and as the bogie frames are FUD they have to be prepared carefully.  I use an axle shaft with an angle flat cut on the tips to act as a reamer.

Test fit of prints on bogies which are now complete.  The paintwork is quite involved and will need several coats of paint and a lot of masking, so this was my first chance to put it all together to plan how to go about the next stage.  I have also invested in a second Colas Class 66 to drive the completed train.  For some reason I just don't like the Freightliner green/yellow livery and as Colas has a current contract with Network Rail its more than a rule 1 choice.  Incidentally the MFS-100 below is primarily for continental use and in the UK they use the MFS-D which is shorter, however, there is no reason not to use MFS-100 as its only a matter of time before we upgrade to them.

Looking forward to your progress.

I'll go back to my RTR Trainset now  :(

Step one to form the steel lining and conveyor of the wagons.  Tamiya spray gunmetal is a very nice metallic and is ether based so can go straight on FUD.  The surface is also gloss and hard so masking should not be a problem. Next step will be to mask the lower sides and spray the conveyor belt which forms the base of the hopper.  The masking tape will need to be cut with templates to fit.  After that dries I can mask the conveyor and start to prepare the bulk yellow.

Lots of masking and spraying and now they need to dry and harden.  That's the inner lining of the wagons done.  The next stage is to assemble and paint the chassis, followed by a lot of detailing.

Trial fit to figure out best way to assemble.  It needs details fitted, paint touch-up, and paint details.

There are two vehicles I will need to make to link the HOBC to the MFS-100 units at both ends, and here are the gaps.

OK basic units assembled.  I'm going to give them a good going over to tidy up the FUD.  Paint and filing goes a long way but the paint lifts fibers that I will now remove with a fiberglass brush.  The paint "The Army Painter" "Demonic Yellow" is a good match for Network Rail (how appropriate  :D) and comes as an undercoat spray can and a 100% matched acrylic paint, makes this task very straightforward.  I will also add a few metal plates to ease the slight curvature of some of the chassis.

Once I am happy with the paint details the models will get a spray of Humbrol enamel gloss varnish.  This is a very effective surface leveler and prepares the surface for transfers, after which a final spray of Satin varnish will give a good final surface.

 :D If you want people who are a few packets short of a load, they are all up the road from me at the castle today.

The real train can have upwards of 54 wagons of which 44 are the ballast wagons.  I think 10 is enough and even this gives a 20 wagon train, more than enough for two Farish Class 66 to move.

A bit of steam heat and brass plates to remove the curves.  This is important as the offload ramp would be well above the loading gauge if the curves remain.  It is worth spending a bit of time anticipating what the 3D printed FUD will do with time.  It will curl if it can so now is the time to strengthen it.

Given the double articulated design of the bogies I decided to give the first unit a test run.  The result was very successful and showed that I need 0.5mm washers above the combined articulation units to allow them to tilt and adjust to points and the inter-board connections on our club modular layout.

Looking good. They still look a little large next to the 68, but I admit I've never studied the prototype that closely.

That's what I thought as well until I checked them against drawings.  They are absolutely on the limit of the loading gauge for main lines and are restricted on some routes due to clearance

this photo shows how much clearance under overhead wires.

Hi,

Do you know of a source for drawings of the MFS-D and -SB?

Eldest son is attempting a CAD from photos, but could do with more accurate measurements.

Its a Japanese product for flower arranging.  I bought my roll in a Japanese "Pound shop" in Kuala Lumpur.  :)

I have had it for years but this is the first large scale use I have found for it.  I'm always on the lookout for special or unusual materials or tools, even on holiday.

All the hydraulic pipes have now been added and I have given them a coat of gloss varnish to smooth the FUD and to give me a good surface for transfers, which are next.  Following that a few details will be added with paint before a satin varnish.  Its a slow process as the varnish needs 24 hours to dry on each side before handling.

I have some different gauge flower arranging wire in my kit. I bought bundles of foot long lengths off ebay for a few pounds - Nots sure what the thinnest is, but I guess it will be of a similar gauge. I've mainly used it to support 'forest in a box' trees. Oh, and thicker stuff for drain pipes etc.

From the OP (where I learnt what an HOBC was) I have been following this with interest (a) because the modelling is so good and (b) 'cos it's going to be a monster.
I'm really looking forward to seeing a vid of the finished article running (and this from a dyed in the wool transition era modeller)

It will be running next year at the Berkshire Area Group NGS Show on our modular layout.  I will post the date soon, we are just booking the hall as we speak.

Hope you make a vid as that's a helluva way from Lankyshire :no:

Yes, but I will need to do it on our club layout to get it all in. :)

Almost there, here is first one with transfers and satin varnish. 

I am just awaiting some black anodized washers in the post to replace steel ones, spacing the bogies, that are visible and I will bolt then all together.  Final task will be to glaze the cabs and fit either space bars or couplings.  With the washers she sits very nicely on the track.  The entire train will have 60 bogies including the two locomotives.

It looks so like a praying mantis or similar insect.

In the background I have been collecting a few more components ready to work on.

The tool wagon which is necessary to fit between the front MFS-100 and the loco or the chute of the MFS-100 would hit the loco cab.  This is part of the Modern Image Models track relaying train 3D print and I can swap it between trains depending on what I plan to run as the markings are identical.  It has a basic undercoat to show were the work is needed to improve the surface texture of the print.  The track laying train is a future project.

The two Farish class 66 that will get Zimo sound chips (my thanks as always to John at YouChoos).  I'm going to follow the YouChoos recommended modifications to fit the sound and this may be useful to some in itself as they must be completely dismantled to cut back the metal frames to fit the speaker.

My rough calculations suggest the longest road we have in the fiddle yard is 13 foot. Is that enough?

Kirky
Measured the longest road in our fiddle yards last night. Only 12 foot - huh, I thought it was longer.
Nevermind, 3.5m = 11.4 feet so we should be ok. If it ends up being longer, we'll have to split it between two roads.

cheers

With the 20 coupling spacings through the train still to be determined it can still change in length by 10-20cm.  If I'm lucky I should get the aluminium washers that will allow me to mount up the bogies from China this weekend and then I will see what spacing is required.  I will be using fixed bars in rakes of 2 or 3 rather than couplings for every end.

Anyway the MFS-100 bodies and bogies are now complete and I am going to move on the the HOBC itself.

OK wheels on. 

I ran a simple haulage test given the wheels have not been run in or lubricated and a Farish class 66 will shift 6 units and two all ten.  On this basis once I have used poly-carbonate lubricant on the axles and run them in I should be OK with two locos for the entire train, if not I will just have to run it with three class 66's  :D

poly-carbonate lubricant on the axles

Que??

Better than normal loco lubricant?

It’s an oil that does not eat plastic as it is a dry lubricant of polycarbonate molecules.  I used to use it to stop squeaks on British Leyland internal body panels.

I didn't follow this thread initially as it wasn't really in my realm of interest. Having 'forgotten' about it, I clicked on the latest posts, holy cow!

Impressive doesn't even come close, I feel very humble as I slowly assemble my 6 wheel x-fish kit.

Will definitely be following this thread closely from now on.

I wonder if Modern Image Models can be persuaded to sell this separately and add a second frame to the other end.

There’s also a different wagon for some of these tool wagons, deeper sided, does anyone know what these have been converted from?   (I don’t have a photo, but a quick search of “network rail YSA” brings them up. They look annoyingly familiar).

Best regards

Iain

Hi
I thought that this may interest you on how far I have got on the cad design for the MFS-Ds it has taken me about 2-3 weeks to get this far.
Thanks to Snowwolflair for sending us the designs for it.

Looking very good.  Even although its early if you are planning to print them on Shapeways it is worth downloading them to see if it passes the material design rules.

I have already tried them on shapeways had a bit of a problem to start with but they now work. Hopefully going to get a test print soon I will post a picture when I get it.

I have started on the block color s for the HOBC itself.  A lot of repetitive masking  :worried:

I have nothing but the highest respect for those of our members who produce such amazing models.

I [briefly] tried 3D models many years ago, but gave up with the resulting pebbledash that I never seemed to be able to totally get rid of.

Test print is now on order in fine detail plastic. Note the previous images are not the design I am as they are missing the finished cab and I have also added some more rails to the side.
