According to Freight Locate, 6M06 runs today, 1,800 tonne load, timed to run at 134mph :roll:

Its to do with people in Network Rail Entering in MPH Instead of Miles Per Hour.

MPH is Miles pre Hour :roll:
ITYF it is a Metres per second vs Miles per hour fault.

For clarification, STP paths are fine - the problem only affects vSTP schedules,It is to do with the way the planners enter the details for STP paths.
Source? Have Freight Locate actually said that?According to Freight Locate, 6M06 runs today, 1,800 tonne load, timed to run at 134mph :roll:
For clarification, STP paths are fine - the problem only affects vSTP schedules,
which are created using a different system to 'normal' STP/VAR schedules.

. . . can someone explain what midlandred is on about?
It is to do with the way the planners enter the details for STP paths. Somewhere along the way there is either a data conversion that isn't working right, or the software is correct and data is being entered in the wrong units.
But it is known that the large values that are displayed all have a direct correlation to typical mph values, i.e. 134 is shown when 60 is meant, and 168 when 75 is meant
Anyway, as a thank you to ALL who took the time and trouble to reply, here is said train passing Oddington this morning

Great shot at 134 MPH! sorry, couldn't resist

Well I reckon you're exaggerating, it looks no more than 122/123mph to me
It seems yet another backward step for the railway when you consider that we had a couple of NIA van sets in around 1999 that, when paired with a 90, were 110mph capable
I was under the impression that the gains from increasing the speed of freight weren't really worth it due to the cost of getting all that unpowered weight to that speed in the first place, and then the extra energy wasted in slowing it all down again.

Possibly, although if you can run a freight train at 110mph (or even 125mph) then it would make pathing a lot simpler on mainlines.
The gains aren't for the freight services themselves, it's in making pathing much easier and increasing capacity in mixed traffic lines.
EDIT: I see Domh245 beat me to it.
Reducing the speed differential between freight and passenger services makes it less likely that the freight will need to be looped to let the passenger service pass. I'm willing to bet it could be possible for a 125mph stopping passenger service to follow a 100mph non-stop freight most of the way up the WCML.Only makes it easier when they are at a high speed and stay there. Soon as you hit a hill or have to slow down or accelerate then its game over.
I did say non-stop!Of course stopping a 2400 tonne freight from 90+ in the available signalling sections might be a different kettle of fish.

Even if it was distributed traction (either freight EMU or top-mid-tail loco working in multiple)? This is a thought exercise, not a practical planning exercise....you would stand no chance of keeping infront north of Preston.
