Hi Richard, the possible swiss origin rings a bell with what i had read years ago, when the class 56's were being constructed. so you could be right.
I know slightly veering off topic but think the first few DA 60s were built in Switzerland - possibly someone can confirm?

Are the new bits (power units, cooler group, roof section containing silencer, etc) identical and fully interchangeable with those on a Class 66? From looking at the photos, the roof sections so appear to have the class 66 roof profile.

Will they also have engine driven compressors like most GM powered locos or retain originals (like 57s?). Back to Romanian link the GM re-engined DA60s appear to have engine driven compressors the amount of times the unloading valve goes off.

Some updated photos on WNXX (subscription section) today, 56031 has replacement structural components in place and the cab ends restyled, new light clusters and new buffers while it no longer has its grid, underside equipment and roofline sections have been fitted with glazing and bodyside grilles to come, 56311 is next and is on refurbished bogies but waiting for the roofline to be done

THe new roof sections do look very similar to those on a Class 66, but difficult to tell for sure whether they are identical.

It also has an AAR multiple working socket in the middle of the yellow panel

I'm surprised it has a yellow panel at all, especially since it has had new lights. Does it have a top light?

There doesn't seem to be any intention to fit a top light as the loco appears at this time, I find it very unlikely that they would cut a space for it now and, presumably, make changes to the wiring. In their current (non)painted state there is no indication of whether there will be a yellow panel or not

Looks to have lights in the same places as previously - headlight just below the windscreens, in the centre, and light clusters lower down to either side.

The avoidance of yellow panels seems to be a preocupation of passenger operators - none of the freight operators have bothered with it: DRS has them on the 68s and 88s as part of their livery, despite the yellow technically not being needed (the TPE liveried 68s do not have them)

The light just below the windscreen is the top marker light, the light clusters lower down include headlights.

Well done the freight operators!

Given railway preoccupation with safety, I find it amazing that an existing safety device that costs nothing and has no failure mode, has been authorised for removal because a new device has been fitted, especially as this new device DOES have failure modes.

I doubt the roof sections are identical between 66 and 69. One reason is the class 66 superstructure is purely a steel "shed" over the innards, whereas the class 56 bodyshell is stressed skin over a frame. Although the roof section from cantrail height is removal for heavy repairs, it might need to be more rigid.
