>>> keep a close eye on this tram in kazakhstan. right off the bat, we have an incident involving the tram running right into that vehicle. but the tram keeps going. it doesn't stop. and a person recording the video notices and starts chasing after the tram. >> is this a runaway tram? is this thing out of control? >> that is exactly what's happening. the tram is unmanned at this moment. and it's going very fast through the streets, hitting cars along the way. >> are there passengers on board? >> it's not clear whether there were any passengers in the tram. it's possible that there were. >> you notice the doors were open. those doors shouldn't be open while it's moving. >> the operator of the tram got out, some reports say to fix something. the tram is going. it's not stopping. and watch what happens as we start nearing a very densely-packed street. >> oh, gosh.
