Adelanted Services? (18/02/2008)

My favourite seat on a HST^▸ (High Speed Train) has been and always will be the 1 in the single one in the TGS. No-one to sit next to you - room for your bag nesxt to you as well.

Okay, qprrule, you get a view if you are lucky enough to bag one of the tables, but who will win the race from the barriers at Paddington on a summer Saturday? The family with children and luggage in tow, or the surfer types off for a weekend in Newquay?

Whoever has the reservation actually.

Same train today 08:00 off Maidenhead? 2 * Adelante.

That's three days running.

But running about 7 down.

Oh, I'm sure he will be: I think it's d_m who's the bad influence!

Thursday: Same train 2* Adelantes.

Passed 08:05

The books are open can FGW^▸ (First Great Western) make it 2 * Adelante for 5 concecutative days?

Would that be a record?

Does anyone travel on this service?

What's the load like?

What about next week?

Isn't it exciting?

Friday Same train 2* Adelantes.

Well FGW^▸ (First Great Western) have done it provided a 10 car train for 5 concecutative days.

Just goes to show that if you have enough spare units to cover the diagrams you can run the timetable with the correct formations.

Of course the accountants don't like spare units because they aren't earing a penny siting in the siding. However, the maths is against them because you can't expect 100% availability from a complex mechanical object however good the maintenance.

It's a question of of what percentage utilisation  you can expect. If there are 3 adelante diagrams and 5 units then that's 60% which is probably poor.

However if there were 18 diagrams and 2 spare units that's 90% which is probaly pushing it.

Of course it you also have to factor in the miles per failure and the expected diagram miles but the maths is relatively simple i'e the more relible the unit the more miles it can run between failures so lessening teh need for spare units to pick up the diagram .

It's called operational research which we (British) were pioneers of during WW2 but seem to forgotten all about when it comes to planning nowadays. Of course during the war it was calculating the mininum number of bullets needed to kill one enemy soldier. It's an astronomic figure.

Try explaing your lack of performance in those terms to your significant other.

Impregnation rates probably work out similarly.

Surely 2x 180 is better than an HST^▸ (High Speed Train). More seats? Better acceleration?

But there is the vibration.

The now almost legendary 2x180 formation (one set with FGW^▸ (First Great Western) markings scrubbed off the sides) was sitting in Oxford carriage sidings at 10am today, presumably waiting to work the 10.30 to Paddington.
