Traino 48's

My dad and Mr Phil was driving taxis together in Campsie a long time before. He bought all his trains from him he told him. Now he can see the reason is the nose is too long and makes wrong angle. too bad.

Yeah just a black blank on Firefox
But on Explorer it does a great representation of a piano accordion!
Very Happy

Thanks Allan

Very interesting indeed & from my old farts maths I come up with the following.

Looking at the drawings from the extreme outside of the edge of the nose from the cab to the tip of the hood is 10 3/8" which is the internal corner support bracket but the actual external start or outer part of the edge on the radius its 9 1/4" the radius then at its minimum at its straight section to the middle is 6 3/8".  EDIT in Actually the inner part of the radius is 5 5/8" not as noted 6 3/8"

This means that the most the end of the nose would be from the beginning of the outer radius 5 5/8 with the other on being part of the main radius itself. There is something like 3 3/8" used up in the edge curves, spread over 5 5/16" being the full radius there are 3 points of measurements in the radius of the edge.

In scale terms of HO, being 3.5MM to the foot, the means there would around   2.8 mm from the beginning of the inner radious, to the front of the nose at its extremen edge. From the start of the external radius would be approx 2.8mm from the nose protrusion  but from the end of the radius a 1.76mm difference extension to the nose outer nose end.

Others who are into maths can interprete better, but for me, to get a difference in the length from the outer end of the side of the hood to the overall length being under 2mm in difference is doing ok & it would possibly mean the more noticeable angled models are perhaps the wrong ones.

Well that tells a story doesn't it?
Mind you that is a dramatic angle compared to the model.  And not really showing up  on the prototype pictures I can see. Engines this old would have been rebuilt many times over the years. Were their changes?
Or were the engines actually built exactly to plans. Architects design buildings and Engineers come along and have to find a way to build them. Many modifications can take place. The Clyde B Class looks to have an E3 type EMD nose on older drawings I have seen, and don't even go near the VR drawings of the L Class unless you have factory drawings.

I wonder if the 45 Class had the same design shape. If so the Auscision model looks very flat as well ??

Allan the pictures of original Trainorama 48 engineering samples are now not available. Was the nose ok on them?

I have no idea. I was not involved with that project.

I'm not going to get into the "mass-debate" on the angle-of-the-dangle and/or how many inches the point of the nose is ahead of the corner etc....

However, looking at the photo inside the cover of the 48 class book as well as the Greg Edwards drawings on pages 40/41, I am completely satisfied with my Trainorama models.

The large, full-spread photo on the end papers is particularly revealing as it shows 48105 on Goulburn turntable
