I've decided to have a play with a thread rather than a blog for a bit. I always liked the old work bench threads, let's see if this gives me the kick up the backside to keep projects moving forward
Previous work was on the blog here: http://www.rmweb.co....60-ewsjos-blog/
Anyway, last week I had an idea. Whether it's a good idea or not, I don't know...
Recent deliveries of stone hoppers have more than a passing resemblance to the current designs of coal hoppers. I have a few hoppers that I picked up cheaply, so didn't mind hacking them about. I've got a nice set of RMC hoppers, which I felt could do with a bit of variety. All this sounded rather worryingly like a plan...
Right, so first up here's a piccy from Flickr with the kind of mix I'm looking to achieve. http://www.flickr.co...in/photostream/ A set of RMCs, with a couple of EWS wagons thrown in, plus a lovely KPA. Towards the back are a Cemex blue and grey IIA as well as a Cemex and an EWS HOA. Add in the fact this train can occaisionally produce a 60 and we're onto a winner!
I'm going to start with an IIA hopper, this looking more involved than the HOAs. These wagons were ordered by EWS for their contract with Cemex, orginally operating off Peak Forest with the HOAs, displacing the RMC JGA hoppers, but as shown on the link above have migrated elsewhere, too. A batch of identical wagons went to Nacco and VTG for lease to Mendip Rail, which due to living where I do, I have many more pictures of, so will be using these to illustrate at times. The wagons were built by Wagony Swidnica, part of Greenbrier, in Poland, the same people who did Freightliner's HHA coal hoppers. Looking at the side and end profiles, there's clearly a family resemblance, and that's where the idea begain. Here's a quick bit of Photoshop work to highlight the work involved, with a Mendip Rail liveried IIA to compare with. Modelling those "breadloaf" buffers could be interesting...
So, from the top down:
Everything above the red line is cut away, this will be replaced with a 6mm wide piece of plasticard as the IIA has this as a single plane, as opposed to the two on the HHA
5.5mm up on the flat bodyside needs to be a horizontal groove. I have made this 1mm deep, with the remainder of the original bodyside above this at just under 1.5mm. On the prototype it is at a 45 degree angle, but on the model I have simply represented it by putting some flat plasticard behind the gap
Top shows the unmodified side, bottom has the top angle cut off and the groove added. Looking back it may have been easier to file this groove in...
The dimensions show the IIA is much shorter than the HHA, most of this is lost by loosing one hopper bay, but additonally each bay needs shortening by 3mm.
Here's current state of play, showing the inner moulding having lost a hopper bay, but still needing each remaining bay shortening
This final image shows the difference in length between an HHA and a JGA stone hopper. The IIA should be slightly longer than the JGA if I'm remembering rightly
I'm keeping my eyes open for some cheap IIA/HYA (Fastline/GBRf) coal hoppers to do some HOAs once this one is done
More soon!
