I have noticed last night that the N/S bound Sleepers are carrying new reporting numbers, 3 digits and a W , what would the W mean ? I know they are digits but in my opinion it has took the shine off the both sleepers :( Regards Dave1954 .

They are randomised headcodes used by RTT etc... They Haven't changed the real Headcoades.

Headcodes are in the format 0A00. First number is the class of train, a letter to indicate information about the train's routing (generally) and then two further ID numbers to identify the service.

I can't understand why on earth a train running under a different headcode would in any way take the shine off anything.

Indeed RTT do not always show the correct details, and such a 'headcode' would not be recognised by staff (or ARS!) rest assured all the hedcodes are as they should be :)

All headcodes continue to follow this format.

I think Sleeper workings are now in the database that RTT accesses as freight workings, hence the random gibberish. Don't ask me how, they just are.

You should be able to see the correct reporting numbers if you read the service details, so in that respect, they are unlike freight workings. 1M11/1M16/1S25/1S26 are still the correct reporting numbers for the four trains concerned AFAIK.

Why does RTT randomise the freight ones anyway? Is it for security?
Commercial confidentiality.

Freight services are anonymised by scrambling headcodes
(and removing the two digit FOC operator code) to make it
as difficult as possible to connect RTT schedules to specific
FOCs/flows to prevent monitoring/collation of commercially
sensitive data regarding the number of trains/tonnages moved
by each FOC to and from power stations, quarries, etc.

Unfortunately, it also has the side effect of hiding headcodes for
innocuous trains such as railtours, test trains, mail workings, etc.

Can anyone shed any light on why GBRf headcodes show on RTT?

Anyone who is that interested / knowledgeable can work out who is operating a service can very quickly.

Frontline GB staff have started using RTT on their mobile devices
(presumably cheaper than paying for Genius mobile licences?! :shock:),
so GB asked NR to stop scrambling their headcodes.

But I think its very unlikely that the far more secretive DB, FL
and (especially) DRS will follow suit, though!

I would dispute that.

In many cases, I agree that the destination/origin of freight services
are handily appended with the name of the FOC these days, but that
isn't always the case, so unless you already know who operates a
particular train/flow, you can't reliably work it out from RTT,
which is the whole point of the anonymisation process:

https://ico.org.uk/for-organisations/guide-to-data-protection/anonymisation/


Also, there are occasions where the locations displayed on RTT can
be misleading, such as Whitemoor yard/VQ, which always shows as
Whitemoor GBRf, even for trains operated by Colas/FHH, because
GB are the operator of the yard.

There are many other, similar examples elsewhere in the country,
so to reliably indentify the operator of all freight services,
including the hundreds of STP/vSTP movements which run
every day, requires a vast amount of additional knowledge
and information not available in any of the open data feeds.

As long as that remains the case, the FOCs will be happy
that the finer details of their operations remain confidential.
