Obviously that route is silly, they can only just about max out at 75 as it is let alone work a booked 90mph diagram!
All "West" mainline diagrams are timed for 75mph, the first Bristol-Penzance service is booked as a 150+153 and is given the same amount of time as the booked 158 turn. I THINK all of the Cardiff-Pompeys are timed for 75mph aswell.

I belive so, as all the 150's can near enough keep time on there, just they don't arrive as early because they loose the slack

That would sound right because 150s do occasionally operate Cardiff-Pompey/Brighton. There probably arent many places on the line where you can you could do 90mph anyway.

Or specify front unit only for SJP!

All very well, but if anything is wider than the single leaf door then it can't get out!

The bad thing is where you are in a 90mph unit and the driver still only does 75 on a section from Taunton - Exeter (speed limit 100mph)

I'm still pinching myself that this swap with Northern is happening and that Dft think that people won't notice this swap of 12 of our 158s with 12 Northern 142s. Crazy.

The only units capable of 90mph are 158's, also, if there is a 75mph unit coupled to it then it has to stick to 75mph, 158's do go 90mph along that stretch and a Exminster. How do you know they only go 75mph? are you a driver or something?

but 158 engines rev lower because of their higher top speed and the automatic gear change into direct drive is a at a higher speed.

The first Bristol-Penzance is usually a 158 but hardly ever 3 carriages- is one taken off at Exeter?

The FIRST one down arrives in Penzance at 1020 and is 9 times out of 10 a 150+153, the second one down gets into Penzance at 1120 and is usually a 158. The 153 off the first one is detached at Penzance and is coupled to the 1242 Penzance plymouth which in turn forms the 1557 Plymouth to Penzance service which is the commuter train from Truro down.
