I took a ride on the BEL train today.
The full loop around Yangon took about 2.5 hrs. It is a bit slower than DEMU. I also noticed that the locomotive doors were closed, unlike before; when I asked about it, They said that the driver's cabin is included AC this time.
A video clip showing the conversion of YDM.4 DF.1300 diesel locomotives into BF.1200 battery electric locomotives. I also noticed about Talbot BEMU conversion in clip.
