That would be the same now...the unit plugged into the socket now won't protect your equipment against that type of surge....they aren't fused.

The document may have had a typo. Or I made a typo when taking notes (Which I suck at anyway so is probable). It was an internal FGW document and FGW's proofreading skills have in the past left alot to be desired... ::)


I flagged this up when looking at the document myself! Both of these things infact!

The Disabled Access Carriage (TSD) I spotted immediately as I knew it didn't have 82 seats. It was suggested that FGW are including the Flip Down Seats opposite the disabled toilet and elsewhere in that area in the whole number. I was not inclined to agree and think this is an inadvertent oversight.

Unless FGW plan to remove the disabled toilet from Coach C... Can't see that being popular amongst Disability Rights Campaigners at all... So I am not even going to suggest FGW might even consider such a thing!

I also doubt that 24 seats will be fitted into a full kitchen which leaves 1 of 2 possibilities.

FGW are reducing the kitchen sizes in the Buffet (Seriously unlikely in my opinion considering the hard marketing of the Pullman and slowly improving of the Travelling Chef services)

So I think it's another oversight as someone hasn't taken into account some Buffet Cars only have 17 seats.

Rhydgaled, do you know how many full size Buffets FGW have in their fleet? I think I will edit my original post as a speculation that FGW have got that slightly wrong.

Slightly off topic. But with regards to the FGW Quiet Carriage in Coach A. Did FGW consider making this a TC for a small section of First Class Seating for a Quiet Carriage? Thus making 1.75 Carriages of First Class (.25 being in Coach A)

Of course that wouldn't be great for complimentary refreshments as you'd have a bit of a walk to Coach F or Coach K ::)

I wasn't too clear in what I was trying to say there. But that's not 100% correct.

5vDC and 12vDC on a USB Port from a Laptop if the port malfunctions is enough to give you a nasty boot. The laptop will be fused at the charger plug (Unless you've bought a cheap Chinese clone adapter which you should throw away immediately as they are NOT safe!)

An example is plugging in a USB Data Stick. If the voltages on the port surge you'll get a bit of a sting and then a nervous breakdown when you realise you've destroyed your USB Data Stick. Anyone who says that doesn't happen should take a backup of their USB Stick right now and stop being so naive!

In this case, 47 seats with 2x USB Ports each = 94 USB Ports. You would have a professional PSU providing that which would almost certainly be fused. But someone elses device on a USB power rail can affect other devices nearby... Rare yes, Have I seen it happen, once.

Of course I am sure FGW have considered the risks here and decided it's worth it. But that is the same FGW that is only just starting it's rollout to Windows 7 so I will sit on the fence for now :)

But you can't charge a laptop from a USB port can tou? Doesn't carry enough current, hdmce why there's an adapter that plugs into 240v.

Ipads & mobiles can charge iff usb ports, and do. Those I was referring to - they just currently plug into a usb port on a 3pin plug (and its those that aren't fused!)

That's not what I said. That's not quite what I meant... I meant charge a USB Device off a laptop which you can do. If the voltage from the laptop gets too unstable, the Laptop's power protection (if it has any; most do) should kick in and and cut the power completely. Hopefully this happens before it fries your device...! Of course there is a very large difference between what a computer should do and what it actually does...

Desktops do this too. If a device connected by USB or Molex Internally malfunctions then the PSU should cut out and then not allow the machine to power up.


some aren't fused... Which is why you won't catch me using one that isn't and I'll charge off my laptop instead. I'd rather lose an hours work than fry my mobile/tablet device!

I think we're going off topic again. What I was alluding too essentially was that if a passenger plugs in their device and it spikes another nearby and blows a fellow passengers device... I doubt anyone would be very happy!

Just like in my local youth centre where someone blamed me for slowing the Internet down because I was watching something on YouTube... Completely overlooking the fact I was connected via a Cell Network and not WiFi ::)

Can you point me to a usb-socket plug with a fuse? I've never seen one on sale...you're right, everyone should be using them. Apple's own product isn't fused, that is what I am using

Actual replaceable fuses are very last year, how many people would carry spare fuses or know how to fit them?

Almost any consumer electronics should however be electronicly protected against over current and possibly overvoltage. Such protection is normally self resetting after a fault without any attention .

Mains voltage transformers or power supplies that fit standard sockets MAY incorporate a fuse, but this will often be non replaceable and sealed within the equipment without any provision for replacement. Any failure of this fuse will therefore require replacement of the transformer or power supply.
This not as silly as it sounds since the fuse should only blow in case of failures that would in any case require a new transformer.

Cheap imported transformers/battery chargers/power supplies may have no fuse or other protection and can therefore fail with explosive violence or catch fire.

I think you'll find that 3pin plugs designed to carry a certain current, are still legally required to carry a fuse - and yes, I think most adults still know how to change one!

In the case of a 13 amp plug connected via flexible cord to an appliance, then yes the plug should contain a fuse and some people know how to replace this ! (a lot dont seem to know how , I have found numerous appliances discarded that only needed a new fuse)

In the case of a power supply, transformer or battery charger that has the plug pins moulded into the case, then a user replaceable fuse is almost never fitted. There SHOULD be an internal non replaceable fuse or other device giving equivalent protection. Cheap imports may not have this.

Moderators - are we not getting a little off topic here? :D

Here you go :)

Always me that does it eh? ::) :-X

Yes, it is.  ::) :D ;D
