I thought the 158 air con was overhauled a couple of years ago? Is this overhauled kit really that bad again? There's only so much that can be done on a 158 given the design and layout of the equipment, and without sapping more power from the engine.

Happens all the time on Great Northern. Less than five people sat in first class on a 317, sandwiched between two rammed vestibules.

Porterbrook had a mark 3 DVT for sale for years, did anybody buy that? Don't know what number it was.

Where do you get this 'backlog' claim? The work class 91s get at Doncaster is planned scheduled overhaul, no backlog clearing of any sort.

The changeover switch between passenger and goods alters the flow rate of air in the automatic air brake pipe. when the driver demands braking effort with the handle, the brake pipe pressure drops at a lower rate in 'goods' than it does in 'passenger'. Part of the brake system maintenance is to...

I'm surprised that Freightliner didn't commit the cardinal sin of removing ETS capability on their class 90s, like they allegedly did on their class 86s, rendering them (potentially) unusable for spot hire to passenger operators. Or maybe that was EWS.

So off the wires it will have the ETS and traction provided by solitary power car? Non starter. Not to mention the other issues with WCML non-tilt timekeeping, acceleration and all sorts of stuff that other in the know members might elaborate on. Also, some form of TDM modification will need to...

Irrespective of what you pay for the maintenance, the rule book and Caledonian Sleeper's operating manual [should] dictate what sort of defects can leave the depot. For all operators, the type of defects that can leave the depot, where safety critical systems are concerned, is "diddly squat, it...

Of all the depots that are involved in the servicing of the sleeper sets during the day under FSR stewardship, Wembley weren't the worst for getting repairs done. The leap between the odd repair and daytime service exam, to overall responsibility for maintenance, seems to have overwhelmed Alstom...

The Great Northern Peterborough-Kings Cross limited stop trips must be up there, 07:26 off Peterborough takes 62 minutes to cover 80ish miles.

On a gradient with the brakes released, it will roll with the doors open. IIRC the direction controller needs to be in neutral/auxiliary for this to happen. The low speed relay will pick up and apply the brakes at about 3-5mph. I think it is as you say a door/traction interlock so power cannot...

Believe it or not, some trains are actually happier with heavier braking than gentle feathering of the brakes (such as lighter, earlier technique). Certain trains fitted with in board disc brakes actually need discs renewed at shorter intervals because lighter braking does not allow full heat...

1000V DC ETS supply on mark2 and 3 LHCS stock. HST trailers have 415V AC 3phase supply.

I wonder what sort of preparation (if any) Wembley depot had prior to taking over the maintenance of the sleeper coaches from Inverness depot? They were capable of doing light maintenance exams if the days overran and a set couldn't be brought to Inverness in time, as well as minor repairs and a...

Do we know for certain whether the acceleration figure for 185 represents Eco-mode conditions or on all three engines? Is it not still the case that Eco mode is only used in certain routes/times?

Those figures aren't really any use unless they are accompanied by the tractive effort curve, which will give a much better idea of the speed range that a unit is at maximum acceleration for. I don't believe for a second that a 170 with 422bhp/45t per vehicle can out-accelerate the 750bhp/52t...

I remember when I was about 9 years old, a pair of what I think we're mk1s stabled in one of the motorail sidings at Waverley. They had been decked out as exhibition vehicles for the hunchback of notre dame Disney film that was released sometime in 95 or 96. I was more in awe of being on a...

I'm watching too, felt a bit sorry for Ruth last week. She adds a bit of manic personality to some downright dull, predictable candidates. She did well selling the fish salads in week one. Brett got out of jail big time for ruining his team's pitch to sell the successful animal balloons. As did...

Given the quality spelling on the rest of that sign, I guess that was meant to spell "train parting". [/party pooper] :lol:

Mark 2 coaches have tread brakes, which make a very noticeable noise under braking. Mark 3 and 4 coaches have wheel-mounted and inboard disc brakes respectively so are much quieter.
