Metro diyaarinaya qorshe lagu hagaajinayo taayirrada loona soo celinayo adeegga caadiga ah ee taxanaha 7000

Guddiga Badbaadada Gaadiidka Qaranka ee soo saarista dacwadda ayaa bixisa khariidad waddo ah oo loogu talagalay dib-u-soo-kabashada gaadiidka

Qorshaha Metroee lagu beddelayo sida uu u cadaadiyo taayirrada gaadiidka 7000-series (7K) ayaa weli la horumarinayaa, iyadoo lagu saleynayo xogta farsamada ee maanta ay soo saartay Guddiga Badbaadada Gaadiidka Qaranka (NTSB).

"Waxaan qadarineynaa NTSB oo soo bandhigtay warbixinnada farsamada si aan u horumarinno qorshahayaga si aan u bilowno in taayirrada lagu cadaadiyo tareenadan heer sare, oo ay ku jirto ku habeynta taayirrada," ayuu yiri Chief Operations Officer Brian Dwyer. "Waxaan diyaarinaynaa dukumentiyada farsamada iyo qorshaha tababarka, iyadoo si wadajir ah u horumarinayno nooca xiga ee qorshaha soo laabashada adeegga si ay u ansixiso Guddiga Badbaadada Metrorail ee Washington."

Warbixinta baaritaanka ee NTSB maanta waxay u suurtagelisay Metro inay si furan uga shaqeyso sababta dhaqdhaqaaqa taayirrada iyadoo la adeegsanayo qorshe cusub oo ku saabsan Return to Service Plan (nooca 4). Inkastoo NTSB aysan si rasmi ah u shaacin sababta, dukumentiyada maanta la sii daayay waxaa ka mid ahaa warbixin ka timid khubarada shirkadda injineerinka Hatch-LTK taasoo aqoonsatay arrin farsamo -- microslip sababtoo ah hoos u dhaca cadaadiska xiriirka. Khubarada injineernimada gudaha iyo dibadda ee Metrowaxay ku heshiiyeen in la kordhiyo miisaanka ku habboon iyo cadaadiska loo isticmaalo in taayirrada tareenada lagu rakibo taayirrada biraha ee dhidib-yahanada ay u baahan tahay 7K. Sida qiyaas hordhac ah, waxay qaadan doontaa ilaa 36 bilood iyadoo ku kacaysa qiyaastii $55 milyan si loo xakameeyo dhammaan taayirrada 7K.

"Hannaanka beddelka dhammaan 5,984 taayir ee 2,992 taayir oo loogu talagalay 748 railcars wuxuu qaadan karaa dhowr sano," ayuu yiri Dwyer. "Waxaan mahadcelineynaa macaamiisheena dulqaadkooda waxaanan rabnaa inay ogaadaan in war wanaagsan ay tahay inaan dayactiri karno ku dhawaad 20 gaari bishii si aan si ammaan ah u dhisno tareenno badan loona soo celiyo adeegga ammaan ah, joogto ah oo lagu kalsoonaan karo ee gobolka u baahan yahay."

Wejigii ugu dambeeyay ee Qorshaha Soo Laabashada Adeegga ee Metroayaa la hawlgeliyay Janaayo 28, 2023. Wejiga hadda jira wuxuu muujinayaa in taayirrada la cabbiro 7 maalmood kasta halkii laga cabbiri lahaa 4 maalmood kasta, waxayna sii jiri doontaa ilaa Metro ka hesho ogolaansho WMSC ee qorshaha la cusbooneysiiyay. Metro waxay sii wadi doontaa kormeerka adag ee taayirrada iyadoo cabbirka lagu sameynayo gaari kasta oo 7000-series ah ilaa taayirrada dib loogu soo ururiyo heerka cusub ee sare.

"Isbeddelada habka waa in ay noqdaan kuwo ammaan ah oo ula kac ah," ayay tiri Madaxa Badbaadada iyo Diyaargarowga Theresa Impastato. "Waxaan qaadan doonaa waqtiga loo baahan yahay si aan arrintan u saxno, sababtoo ah gaari kasta oo tareen ah waa inuu maro hab adag si uu u diyaar u noqdo inuu u adeego macaamiisheena oo uu taageero shaqaalaheena."
