Class 170 on Holbeck depot in Northern Livery

[cal.n]

And in Scotland, 170/4s are starting to become debranded. As the first HST sets replace 170s and 158s on Glasgow - Aberdeen and Edinburgh - Aberdeen trains in the coming weeks, Northern will get the redundant 170s.

 

 

Edit: just an afterthought, I assume Northern will declassify the first class these units had?

The plan is for 2+4 sets to replace 170s on Edinburgh-Aberdeen firstly, then those will be replaced by 2+5 sets with the 2+4s cascaded to Glasgow/Edinburgh-Inverness. Glasgow to Aberdeen will be the last of the main InterCity routes to get HSTs, though some Aberdeen-Inverness internals will also be HSTs presumably once all the sets are in service.

 

Yes, Northern don't offer First Class accommodation so I'm pretty sure the First Class areas in the 170/4s will be declassified.

Not what the 170 Traction manual states

From experience I can say that 75 mph Sprinters changeover at 45, 90 mph 158/159s at 57, 100 mph 175s at 60 and 100 mph 170s at 70.

 

I can only assume the Traction manual has for some reason mixed the T211rzze transmission with the T211r fitted to 75 mph Sprinters. If a 170 changed over at 45, there us no way it would manage 100 mph, at 2,100 rpm (maximum engine speed), it would only be doing about 75 mph. The reason why the transmissions changeover at different speeds for different top speeds is so that the direct drive or fluid coupling gives a greater speed at maximum revs.

Well someone better change the current traction training and documentation... The one I had the other day wouldn't make 100 anyway
