There are a number of more recent articles but I did not include links as they are quite technical but the University of huddersfield have produced a lot on this subject and by the looks of it part authored by the same guy

Nothing unusual there. The hybrid buses that Stagecoach run in Sheffield had a similar arrangement put in place very early in their lives with all relevant maintenance being carried out by the supplier of the Hybrid system.

 

There is nothing unusual in the maintenance being handled by the supplier of the equipment and this is also very common in the rail industry and they will typically specify a minimum %age of the fleet that should be available for service.

 

There are many benefits of such a contract but what was being suggested was that Stagecoach had not had any significant input into this vitally important part of the contract and therefore any problems were the fault of the PTE/Govt. and "not us gov"

I had a ride on the Tram Train this morning, for the first time.

 

Trams from Sheffield at 39 & from Parkgate at 09 were - again - cancelled until further notice, so only 2 trams per hour with an approx 30 min frequency. Tram to Parkgate departed Cathedral 3 mins late. Had a look around Parkgate (was impressed at the range & no. of shops!) then caught a tram to Rotherham Centre - which departed from Parkgate 4 mins late.

 

Had a quick look around Rotherham Centre then another late tram (5 mins overdue this time) back to Sheffield. Supertram official at Rotherham Central said that the reduced service was due to "technical issues" - I did see a Tram-Train vehicle parked in the depot as we went past & it wasn't the same tram which was damaged on the opening day...

 

Tram-Train on the outward journey (timetabled 09:27) wasn't at all busy but the return from Rotherham (timetabled 11:02) was well used.

Wasn't the original idea many many years ago for the tram train to be run by Northern rail therefore explaining why stagecoach were not involved.

Having the manufacturer on contract for repairs and maintenance rather than your own in-house teams saves money, both instantly and in the long run.

 

In terms of instantly, these new tram-trains will have a lot of parts that require specialist tools so having the manufacturer, who already has them, doing all the work means you (the company) don't have to fork out thousands for your own set.

 

In the long run. Put it this way. If you tried to change a part on your car and in the process broke either the new part or something else on the car then you'd be liable for replacing it.

If on the other hand you sent it to the dealership to do and that happened then that cost liability is on them.

As i said these types of contract are common in the rail industry and are an excellent idea. My only issue was the implication that the contract was awarded with out the input of the user which would be odd if the operator was known - I have no idea if it was originally intended when they were ordered that Northern rail would run them

What actually happened was the driver apparently locked himself out of the cab and they had to send a key by road.

Unbelievable I know but I went to Parkway the other day and the Pid was actually providing correct information and working as intended for the first time in several visits instead of rubbish - I hope that this continues and was not a one off

The sign at Granville Rd (heading away from town) is still regularly all over the place - e.g. the tram towards Herdings Park due at 16:21 is frequently shown to be running on time - minutes counting  down & "Due" then appears at 16:21 - & then it suddenly indicates "5 mins".  Then the tram nearly always turns up at about 16:27 - 6 minutes late - with the sign showing  "3 Mins". at that point..

I think you're right - I see that the Star's tale of derailment now seems to have vanished from their website!

[BigAl1 143]

Indeed the rest of the Pids are still an embarrassment (or would be if it was possible to embarrass the PTE and Stagecoach) however as I understand it the ones at parkgate were provided by Network Rail and on the whole network Rail ones work pretty well (not flawlessly) so it was a suprise in the early days to see the rubish on the Pargate displays

 

"Arriving tram do not board" on day of opening

"contact staf"f a week later (of course the station is unmanned)

Wrong train info a week later
