New Class 93 Tri-Mode

[RPNaylor0301]

Good spot - think I was too quick into revolution's site.

 

At least I can get away without adding catenary for these!

Wait a minute!

What about the classes 50 and 55? Was it that they were not current or what?

Cheers,

As with the locos themselves, Bogie design evolves as time goes by.

 

No sane company is going to reuse a 50 year old design on an otherwise state of the art loco. At the time of ordering the 67s, the bogie under the 89 was the most up to date UK approved high speed Co-Co design, but its design rights remained with Brush Traction and so far the cost of reproducing it by other loco builders has been considered too expensive.

 

However the bigger problem is with UK passenger trains dominated by unit formations there its simply not cost effective for anyone to start developing a high speed Co-Co design due to the low sales potential, you need high sales volumes to recoup the R&D.

 

In fact if it wasn't for BR telling Brush they were looking for a large number of 89s for the WCML and ECML its doubtful that the bogie under the 89 would have been created in the first place!

Mind you isn't it a close variant of that under the 58, 60 and 92 though so wasn't too much  of a stretch for Brush..?

The 60s and the 92s came after the class 89 so if anything the class 89 bogie could be said to be the pioneer for those two classes.

 

The class 58 was developed by BREL / BR and not Brush so is no relevance.

 

However the biggest thing you ignore is the 58s, 60s and the 92s bogies were most definitely not of the high speed type! They were all about the ability to shift heavy freight trains up to a maximum of 75mph.

 

The locos being ordered by the ROG are for transfer moves, logistics / intermodal and charter work - the latter two needing locos capable of sustained 100mph running. A Co-Co design optimised for heavy freight haulage is a world away from whats needed from a high speed passenger variant...

Beyond them "somehow" being the precursor of the design... Brush clearly took that design and produced a related high speed variant.

Absolutely ignoring nothing, just noting the related nature...

Brunswick Green?

And I wonder what significance of that could be...   🤔

Looks good , would have preferred blue to green , but I suppose it has to advertise it’s green credentials
