The need to place an order with Shapeways for components for the PTAs has seen some frantic work in completing a few other bits that have been on the back-burner for a while. One of these is a version of the LTF-25 bogie designed for the national power JHA/JMA:

There are actually an awful lot of differences between this bogie that is fitted to these Finnish-built wagons and the one fitted to the ARC JHAs (built in the UK). Again, there are two versions of the bogie, one with a hand wheel and one without and again each of these has differences when viewed from the left side or the right side. The picture above shows the hand wheel version.

 

Here are the main difference between this version and the ARC version:

  1. The main frame has a deeper profile box section onto which the secondary air suspension sits.
  2. Mounting points for the dampers are totally different
  3. Different hand wheel mechanism and brake application indicator board positioned side-on
  4. Larger cable stays

Like the ARC bogie, this version also makes use of Colin Craig wheels and hand wheels plus the sequin and o-rings for secondary suspension. I have cut pilot holes for Colin Craig hand wheels that are in different positions on either side of the bogie.

 

Here is a prototype view for comparison (albeit from the other side):

Thanks Chris. Hopefully I can answer that soon as I've ordered two pairs as a trial this afternoon.

 

Now where did I put the HHAs and the paint stripper...?

 

Whose paint and transfers did you use for yours in the end?

Hi, yeah i used the fox transfers which i think were v accurate apart from the hopper door control labels, on the whole though, they were all there and i think 1 or 2 of the real smaller details i omitted. The paints were from precision, they do all the correct NP colours, though they do need a fair bit of white adding to get the faded look. it has reminded me actually, the silver/grey paint seemed to come off the HHA's in a right old globby mess, enjoy!
