Class 70 detail differences

Apart from the obvious removal of the "crease" in the cabside, are there any other detail differences between 70001-70006 and the later delivery of 70007-70011?

 

No comments about 70012 please, as that's been done to death elsewhere.

Related to this - Replica Railways now produce a transfer sheet to renumber your 70 between 001-011, including the yellow end numbers.

No excuses now for all those 001/003/006 models.

Cheers,

How long before 003/006 renumbers as 001 come up on a well known auction site as "limited edition certificate missing".

 

Purchased some Phoenix Freighliner yellow today so I can get rid of that horrible cabside crease and welded panel.

 

Cheers,

Mick

I've just had a thought, not being in an area that sees regular 70 haulage, could that crease be a result of some minor damage?

Thanks Chard, I've had a look via google (class 70 cab) and the first picture that came up was 70006, with the crease on the secondmans side!!

I'm now puzzled as to why GE felt the need for the crease.

The sticking out bit below the front windows looks like an energy absorbing feature in the event of a collision. The crease may be part of this, perhaps encouraging the cab side sheet to crumple rather than intruding into the driver space or blocking the doorway further back.

 

...but if that's so then I'm not sure why it doesn't appear on later locos. Perhaps they've just filled it with Isopon?

Pure speculation on my part but ...

 

The crease may be part of the strength of the cab side panels, rather like the automotive industry does. A plain sheet of steel (or whatever else) can be bent more easily than if you introduce a crease along or across the panel.

 

The same idea can be seen on classes 45 and 46 with their fuel tank or battery box sides (not sure which they are, off-hand), where some had the swaging in the shape of an 'x'.

The bit in front of the windows isn't a crumple zone, it has the anti-override units - similar to those fitted on the ends on modern multiple units. They are designed to engage in a collision and prevent or limit vertical movement. As such, they are not designed to crumple. However, they will only work if one Class 70 hits another..... (please no comments about that being a good thing), as they are at differnt height from those on multi units.

We used to put creases in a "X" shape (similar to the Peak battery box covers as mentioned above) in large flat panels holding the insulation on large industrial drying systems to minimise the bowing and vibration. I'll try and contact my Class 70 expert to get an answer.

And a reply from one of Freightliner's engineering staff specialising in the 70.

 

"Just how the metal sheets are fixed to the bodyside diagonals. We had them build 007 onwards with them filled in as they looked a mess. Can't be bothered to fill 001-006 in"

 

Ta to my man.
