It is interesting that when KD makes an ad for any unelectrified line extension, they are still using Pesa Links/SA139 in them, and not 36WEh/bimodal Newag Impuls 2 despite it being newer etc
And that happens even if 36WEh will be the dominant stock on that line, or SA135 because SA139 has too much weird tech that makes it unsuitable for the line.
First ride to Chocianów? SA139. Usual stock? SA135 First ride to Karpacz? 2xSA139. Usually SA134 Ads for Bielawa Jezioro/Góry Sowie? SA139. Usually 36WEh, or SA134/139 if there’s not enough demand for 36WEh.
