RE: New StreetDecks & ADL Enviro400s - X-lines fleet changes
(12 Sep 2020, 6:58 pm)streetdeckfan wrote Correct me if I'm wrong as I'm not too familiar with the route, but doesn't the X1 spend about 4 miles on Washington Highway?
So if we do some back-of-the-envelope maths...
Assuming a straight 4 miles with no difference in acceleration/deceleration the StreetDecks will be able to do the stretch in 4 minutes 48 seconds, whilst the B9s will be able to it in 4 minutes 13 seconds. That's only a 35 second difference. I'd expect they spent more time than that sitting at traffic lights, and certainly not enough to make a difference to the timetable.
I don't know what the difference in acceleration speeds are as I can't find any figures online, but it'd only make the difference in time shorter, as would the difference on hills
Congratulations, you've just passed your Level 2 Maths Functional Skills. Certificate is in the post.
Seriously though, most organisations are looking to save time through Continuous Improvement techniques, not add time.
Imagine if Nissan added 35 seconds to the manufacturing process? One lot of 35 seconds may not be too long, but add the numbers up and all of a sudden one lot of 35 seconds has increased.
Convert that to bus journeys and (excluding any other natural delays), a round trip is over a minute down on where it would have been under the B9's. If the bus is out for 8 hours... Well you get the gist. You've just passed your level 2 maths.
Another example could be the 21 hitting Birtley 35 seconds down due to a passenger dithering on. It hits the first set of lights late, gets held up at the second, has an extra person rock up outside Lloyd's Bank to add to the existing queue and gets to the third set of lights 2mins down.
The main point I was trying to get across in my initial post, was that the overall journey time on the X1 is longer than it was in the past.
In addition to it now being all stops between Easington Lane and Shiney Row now, drivers appear to have lost the flexibility of leaving the Galleries alternative routes.
It gets stuck in the bus link at Wrekenton (as opposed to bypassing it and stopping at Stormont Main Club) and has the extra couple of minutes around Gateshead and the Interchange. Granted the removal of bi-directional traffic from the High Level and removal of traffic from parts of Gateshead can't be helped and has added to the journey time, but the rest of the decisions are internal ones. Internal decisions which have made the trip slower/longer.
Fancy liveries and on-board interiors are only a part of increasing bums on seats. Journey times are a factor too, but seem to have been ignored. Again.
