English: Well, TfW, as the managing and operator partner for Welsh Government, would like to apologise, but I think it also needs to be recognised that, in a very short space of time, Transport for Wales have worked incredibly hard to bring a number of trains back into use. Normally, we operate at about 80 per cent of the entire fleet. There are 127 trains in the fleet, so normally we'd be operating at around about 105, with the remaining trains in for servicing and maintenance. I can tell the Member that, as of this morning, the number was up to 96. We're therefore operating at around about 76 per cent. It will return to normal - back to the 80 per cent - within a few weeks, but I think it should also be noted that the cause of this problem - and I do appreciate passengers' patience during this difficult time - is that we inherited a fleet of trains that have been very poorly maintained, which we did not have full and proper access to ahead of inheriting them, and that, along with Storm Callum, and taking over the franchise in the autumn period, presented huge challenges for Transport for Wales and the operator and the delivery partner. We're also looking into the reasons why this issue affected Wales - the Wales and borders network - more than other parts of the UK. What we have found, and I think I said this in the Chamber last week, is that none of the rolling stock - none of the trains - on our franchise are operating with wheel-slide protection. This is significant because trains across the rest of the UK have been operating with that protection. What we have now learnt is that, potentially, the problems were worsened in Wales because in the absence of wheel-slide protection and as a consequence of a decision taken in 2016 - and this is across the UK - to stop applying sand to rails, it meant that the traction on Welsh rail lines has been worse this autumn. So, that's been another significant contributing factor. I met this morning with Sir Peter Hendy, the chair of Network Rail, and I also met, again, for the third time, with the chief executive officer of Transport for Wales. I received the latest update on services, and, as I say, there have been improvements - significant improvements - in the space of a week, with more than 10 per cent of the trains now having been brought back into use, but this remains a very challenging period due to the dreadful underinvestment in our rail network over the past 15 years.
Welsh: Wel, fe hoffai Trafnidiaeth Cymru ymddiheuro, fel y partner rheoli a gweithredu ar ran Llywodraeth Cymru, ond credaf fod angen cydnabod hefyd, mewn cyfnod byr iawn o amser, fod Trafnidiaeth Cymru wedi gweithio'n hynod o galed i ddod â nifer o drenau'n ôl i ddefnydd. Fel arfer, rydym yn gweithredu ar lefel o tua 80 y cant o'r fflyd gyfan. Mae 127 o drenau yn y fflyd, felly fel rheol, byddem yn gweithredu tua 105 ohonynt gyda'r trenau sy'n weddill i mewn i gael gwaith cynnal a chadw wedi'i wneud arnynt. Gallaf ddweud wrth yr Aelod fod y nifer i fyny i 96 y bore yma; rydym felly'n gweithredu ar lefel o tua 76 y cant. Bydd yn dychwelyd i'r lefel arferol - yn ôl i'r 80 y cant - o fewn ychydig wythnosau, ond credaf y dylid nodi hefyd mai achos y broblem hon - ac rwy'n gwerthfawrogi amynedd y teithwyr yn ystod yr amser anodd hwn - yw ein bod wedi etifeddu fflyd o drenau nad ydynt wedi cael eu cynnal a'u cadw'n dda o gwbl, ac ni chawsom fynediad llawn a phriodol atynt cyn i ni eu hetifeddu ac arweiniodd hynny, ynghyd â storm Callum, a mabwysiadu'r fasnachfraint yn ystod yr hydref, at greu heriau enfawr i Trafnidiaeth Cymru a'r gweithredwr a'r partner cyflawni. Rydym hefyd yn edrych ar y rhesymau pam yr effeithiodd y mater hwn ar Gymru - rhwydwaith Cymru a'r gororau - yn fwy na rhannau eraill o'r DU. Yr hyn a welsom, a chredaf fy mod wedi dweud hyn yn y Siambr yr wythnos diwethaf, yw nad oes yr un o'r cerbydau - yr un o'r trenau - yn ein masnachfraint yn gweithredu gydag amddiffyniadau i atal olwynion rhag llithro. Mae hyn yn arwyddocaol oherwydd bod trenau ar draws gweddill y DU wedi bod yn gweithredu gyda'r amddiffyniadau hynny. Rydym wedi dysgu bellach fod y problemau, o bosibl, wedi gwaethygu yng Nghymru oherwydd, heb yr amddiffyniadau hynny i'r olwynion, ac o ganlyniad i benderfyniad a wnaed yn 2016 - a hyn ar draws y DU - i roi'r gorau i osod tywod ar reilffyrdd, golygai fod tyniant ar reilffyrdd Cymru wedi bod yn waeth yr hydref hwn. Felly, mae hwnnw wedi bod yn ffactor arall sy'n cyfrannu'n sylweddol at y broblem. Y bore yma cyfarfûm â Syr Peter Hendy, cadeirydd Network Rail a chyfarfûm, unwaith eto, am y trydydd tro, â phrif weithredwr Trafnidiaeth Cymru. Cefais y wybodaeth ddiweddaraf am wasanaethau, ac fel rwy'n dweud, mae gwelliannau wedi bod - gwelliannau sylweddol - o fewn wythnos, gyda mwy na 10 y cant o'r trenau bellach yn ôl mewn defnydd, ond mae hon yn parhau i fod yn adeg heriol iawn, oherwydd y tanfuddsoddi ofnadwy yn ein rhwydwaith rheilffyrdd dros y 15 mlynedd diwethaf.
