This is the chassis for Pryds, a model in H0e scale of one of the UHB locos. To improve performance I have made som parts to make the chassis compensated.

I materialise have 3D printed in High detail stainless steel the box for making the chassis compensated and the driverods with forkshaped joint. The thickness of the rods are 0.3mm These parts came out fine and fits with very little filing. The 3D printed rods are a bit broader than the original as evident in the pic. This is my fault and is not necessary. I will file the 3D printed down.

Here is the box for compensation in place in the chassis. The axlebushes are pushed together in the middle. There is no filing or milling nesessary on the chassis. Just drop in.
This is 3D printed parts for a very small and heavy drive unit for moving wagons on the travers. There will be one on each track. The two on the upper left are from I materialise and the two upper right from Shapeways. Material is blackened stainless steel. They have schrinked about 4-5% which gives me problems. Also they are a bit out of square shape. Shapeways are best here. I found the steel to be quite hard and I had problem to cut threads for 1.2mm screws. One solution is to 3D print a larger hole and pressfit a brass tube into it. Then making threads in brass is easy
 Here Is the travers with with 3D printed guides, fixture for holding the gearmotor and the servos for the sliding doors. There is also two servos hidden under the plywood plate on the far end
I use micro switches and diodes to stop the travers at each end. The round milk caps will have off center screws to fix them at the right spot to stop the travers at the correct position.

 H0e and Z scale Mini Meet

In the weekend 17-18 nov. 2018 a Mini Meet was held in Oslo arranged by Hans Henrik Riddervold.
He is the man behind The UHB rolling stock from 1994-96 and later a wast development of american Z zcale through AZL (American Z Line). Participants were Svein Martin Holt , Tor-Jørgen Moskaug (Torsja) from Norway and the german modeller Karl Sinn all with Small Z scale dioramas. Also from Norway Tertittkameratene with their Fremo modules/sections. ( Knut E. Kittelsen and Christer Ritterberg with Stein R. Pünther)

Here is a link to Svein Martins fine pictures from the Mini Meet:

The work with Finstadbru stasjon and sawmill area is  progressing. All the woodwork to the sections are made. All parts are cut after my drawings at a commercial woodworking firm utilising a CNC Mill
It was costly but valuable. Here is two pictures of the test assembly in oktober:

Finstadbru Kassefabrikk (Crate factory)

 Referring to the  Air photo of Finstadbru , the building is to the left towards bottom. To aid in the constucting of the model I use the air photo (ca 1954), older maps of the area (the footprint) and a photo from Digital Museum  At the back in the photo 
Thats about all I have, but I think the size and form will be reasonable correct. Another photo in Digital Museum from ca 1955 show the then newly built saw building with a siding for UHB
Sidesporet til C.H.Aanerud sag og høvleri på Finstadbru er ferdig.
This building also shows in the air photo at middle bottom.

This gave me the idea to make a play wit empty and full wagons in and out of the two buildings.
They are about equal in foot print.  This will make more interesting trafic in Fremo context.

For each building I reserve a space in the middle that can hold 2x3 bogie flats on a travers with two tracks, one for empties and one for loaded wagons. On the end nearest the siding and connected to it, there will be a room for one wagon, loaded or empty. On the other side some interior vill be visible through openings and windows.

Here is the model of the Kassefabrikk so far:

Mork meieri

 Christer wanted this building for a small siding at one of his modules. It is a Funkis inspired building near Mork station on UHB. it was built about 1938. Here is some info of the building:
 Mork meieri The building still stands in a somewhat changed form.

So I have used a lot of time to find out how it looked originally and here is the result so far on paper. It is now ready for 3D printing (another heavy task).



 More to come.......

Hello all,

Well back from an inspiring Fremo meet in Arendal 19-22 april 2018 we have some pictures and videos to share with you from the H0e Urskog Hoelandsbanen branch. Modules/sections are built by:

Christer Ritterberg; Blingsfoss to Killingmo with curved modules in between stations
Knut E. Kittelsen: Finstadbru and  transfer section to Fremo standard with a  small bridge on a short incline (50mm on 1.2m). The total lenght of the branchline about 12m

Rolling stock is Christers with Z scale Microtrains couplers operated with hidden uncoupling magnets. Locos are Setskogen (ultramarine/black) and (Prydz black), both equipped with sound, lights and improved pickup by Christer.
Løftekasser (containers) 3D print from Shapeways designed by Knut. (may be offered for sale at Shapeways later this year)

On the planning/construction stage are new sections at Finstadbru (Knut) and two curve modules  (Christer.) Further extentions are in our heads.

Here are some impressions

Fremo Arendal april 2018 - H0e UHB

Friday, 28 October 2016


Since 1970 I have had a dream of building the Norwegian narrow gauge line Urskog Hølandsbanen in model. 

In 1970 I had some experience with modelling in H0e and I had built a scale model of the Bridge of the River Kwai (from the movie).

I had discovered code 40 rail on a trip to London and found it was correct for 9mm narrow gauge. But I did not at the time know that there had been a tiny narrow gauge railway only an hour drive from where I live (Oslo).

I dicovered the 750mm gauge railwayline Urskog Hoelandsbanen in 1970. At the time it had been closed for 10 years, but some enthousiasts had started a society to save some of it as a preserved railway. Today it is a popular museum with steam trains running in the summer. Five of the seven locos are intact and three of them are in working condition



(See further links at the bottom of this page. Contains a lot of info for modellers of the line. Also a map of the entire railway line and air photos of the entire line in sections (after abandonement)

In the early 1970-ties I did several excursions to the line in company with friends and photographed and made sketches of some of the railway buildings still standing. I was especially imposed at the station Finstadbru up the line. It had close to it several sawmills and a huge amount of sawed plank in stables. Also a huge sawdust pile. 

At Bjoerkelangen I found a very interesting coal house and water tank. 


Also the stationbuilding was intact. There were traces of a siding crossing the nearby river to reach a sawmill. The locoshed I found about 1000 m up the line just before the line enters open landscape with farmland


The Air photo also show two other small sawmills. One is reached by a siding branching out from the mainline near the coalshed. The other further up the line to the upper right in the air photo

In 1972  I  made a model in H0 (1:87) of the station building at Finstadbru. 


Then I did some work on the coal shed at Bjørkelangen. 


Then it stopped. No locos, no wagons, no nothing  was avalable and along came N scale---


So, in 1995 a young man, Hans Henrik Riddervold,  announced four of the locos and many different wagons as precise scale models in H0e. All made by Ajin in Korea.

This boosted my interest for UHB again, and I bought some of the models to start  with. I took contact with Hans Henrik and suggested a loosely organised module/section group aiming to recreate parts of the UHB line in H0e.
He liked the idea and we found a few more modellers interested.
I designed a module /section concept and we started building of the first three sections of the station Finstadbru. Knut Tore Tronrud helped with carpentry of the first section, Stein Ragnar Pünther made a model of the building next to the stationbuilding at Finstadbru and batches of resinmodels of small buildings along the line.



and Christer Ritterberg helped with producing piles of sawed planks----


while I made a model of the water tower at Finstadbru


We took it to a few exhibitilons in and around Oslo, last time in 2000. 
Then life took us in other directions until  Hans Henrik in 2006 announced a big sale of all the remainig models. 

 Crister and I and many others grabbed the opportunity to complete our collection.  Hans Henrik could concentrate on his other model enterprice:


In the meantime Christer had been involved in a group of modellers in the Oslo region namely the "Skaarerbanens venner".  


The group models Skaarerbanen, a frelance Norwegian branchline, as part of Fremo Norway. FREMO is an international european module group.  


He saw the potential in adding a narrow gauge line based on UHB and built a combination station loosely based on Bingsfoss at UHB. Here standard gauge Skaarerbanen meet narrow gauge. He named it Blingsfoss. Then he started adding modules and soon he had a modul based on Killingmo, a small station up the line.

I was impressed with his work and when he asked me to join Fremo with Finstadbru I could not resist. At that time (2014) the rail at the Finstadbru sections were in bad condition, 


but I managed to repair it. I then rewired it to DCC digital control.

 To link Finstadbru with Fremo, I built a transition module. 

At the big Fremo meeting in Arendal in march 2016 we operated an about 10m  long H0e branch. To make this lenght we also had two neutral modules built by the young fellow FREMO member Magne Lundgaard.
