Metro Red And Purple Line Test Trains

[@tntmaster1104]

This is probably what Metro will do once they start testing the new CRRC HR4000 Subway Cars

[@jaydenmamane353]

Agreed

[@sgtdebones]

AC + DC combo testing, interesting

[@LDTV22OfficialChannel]

Wow, they coupled the older DC units with the newer AC units and they worked just fine

[@mikedrown2721]

What happened?

[@sgtdebones]

AC + DC combo testing

[@michaelbilgen2976]

No idea what that means.

[@metrorailinlosangelesprodu4407]

Nothing is happening. Metro just like to test trains but AC and DC are the train models . Metro ran an old train model with a new model. Don’t worry I will make video explaining everything soon 😂.

[@michaelbilgen2976]

I meant what does AC and DC stand for?
