Coupling

[Joanna]

Hey guys,

I am writing an article about coupled trains but I am struggling with finding some information.

What do you think about the future of coupled freight trains? Will the common ways of coupling be replaced by automated/virtual coupling?
If we are going to implement ETCS level 3 one day and get rid of axle counters, how we are going to operate freight trains consisting on coupled wagons?

Thanks :3

Will our implementation of ETCS still go ahead if we leave the EU ?

What effect will a successful BREXIT have on UK railway safety plans ?

And as I did not know anything about "axle counters", the what and why, I looked it up.

Interesting.

yeah, axle counters are so much fun :3

I don't think that leaving EU will have any impact on implementing ETCS. I think that even countries outside of EU adapted the rules for railway interoperability.

Even more fascinating (to me at least) is virtual coupling. I've learned two things today as axle counters were a mystery to me also

There are two reasons why I can see ETCS being delayed, or even not happening here.

1) Europe is pushing us to adopt its own system - ETCS. If we do leave the EU, Network Rail won't have to spend billions on implementing it. Our current government is all out to save money.

2) The UK is an ISLAND. Our trains don't cross borders into other countries, and their trains don't come onto our network. Our ONLY interopability with Europe is via the channel tunnel - and HS1 already has its ETCS sorted.

In short we just don't need interoperability with the rest of Europe because with the exception of HS1 we don't interoperate. We get by very nicely without ETCS, thanks.

Here's a guess.

Before the start of the journey, in obtaining movement authority the freight train driver would program the length (and weight) of the train into the ERTMS cab panel. This is something that many Class 66 drivers do with the loco computer already.

The safety in the system is that all trains must be fitted with the automatic brake. So if the train comes apart the brakepipe will vent and the train will be stopped by an emergency brake application. This will be observed by the RBC (Radio Block Centre), which will slow down and stop the following trains accordingly. The driver must inform the signaller that his train has divided.

If the driver needs to add or remove vehicles from the train during the journey, this information will be pased via the ERTMS panel in the cab before authority is given for the next movement.

any one know what kind of coupler is this?
