Due to arrive Inverness 1350. Some 312 minutes late.
And the other competent person would most likely sign 66s anyway.The 66s are a lot heavier... however, the Class 66 fuel tank holds 3,600 more litres of fuel than the 73/9's (3.4x as big). The 66 also won't be pushing itself at all to haul a Load 8, so its fuel consumption will be considerably less than hauling a heavy freight. The factors noted above were more around range and reliability than cost, though.
The driver still needs to have traction knowledge of the 73/9 as that that's in multi and under power.
If the driver in the 66 didn't sign 73/9s, there'd need to be a second "competent person" in the 73/9.
It was cancelled when it arrived at Edinburgh just before 06:00.Seems to be cancelled now. My first info was from faster route but rtt says it's been cancelled. Nothing on CS twitter page.
Thanks TimIt was cancelled when it arrived at Edinburgh just before 06:00.
Full stock went to Polmadie on 5D26 VSTP - left Waverley at 06:45.
Not really much need to put anything on Twitter - suspect there were more crew on the train than passengers.
Back to Shed and Ed in the morning. Brief Double Ed interlude for 66725 to have an Exam.Inverness portion back to two class 73s again 73968 and 969.
They are when it is two 73s on the service.Why are the 73 not being used in multiple?
They are - the 73 is working in multi with the 66.Why are the 73 not being used in multiple?
Many thanks. I see your point about why not use a 66. Great machines.
Are there any places North of Edinburgh that the sleeper is timed to require >75mph?Limited to 75mph though.
The coaches are only meant to run at 80mph so its obviously not to much of a problem given the amount of times it is looped for other services on the way north.Are there any places North of Edinburgh that the sleeper is timed to require >75mph?
They can run at 100mph and do if the services over 20 mins late iirc. Not sure about the Scottish lines though so may not matter.The coaches are only meant to run at 80mph so its obviously not to much of a problem given the amount of times it is looped for other services on the way north.
I'm sure anyone who signs the routes will correct me but AFAIK (from looking at the Sectional Appendix) the only significant bit of route with a linespeed (for loco hauled trains) of 100mph is between Dundee and Arbroath.They can run at 100mph and do if the services over 20 mins late iirc. Not sure about the Scottish lines though so may not matter.

That's interesting. What were the reasons of switching from the 90s to 92s?Not on the electric sections they don't - Class 92s have a max permitted speed of 87mph.
They did run at 100mph if running late when Class 90s were used, but that's stopped since the introduction of the Mk.5s.
I think 90 mph for 73/1, not too sure on 73/9 but imagine it's the same.What's the top speed of multi 73s?
In terms of energy used its enough to boil around 20 electric kettles.A 90 can provide 475 kW whereas a 92 can provide 540 kW. Does that make the difference?

maths a bit wrong thereIn terms of energy used its enough to boil around 20 electric kettles.
I guess what we're looking for is the hotel power required by a consist of 16 Mk5s - I'm assuming peak load would be near the end of the journey?

Yep that's where I got them from. That's interesting that a 92 is double.Where have those numbers come from? I'm guessing the rule of thumb 5kW per ETS index of 1. That's a guide, that's not the actual rating. And you've plucked the DC ETS rating for 92.
90 is 500kVA and 92 is pretty much double that.
That would be a very slow kettle - most are around 2.4 - 3 kW.maths a bit wrong there
assuming 1.2KW kettles thats 395 kettles on class 90 and 450 kettles on a class 92
