Dynamic next station displays are beginning to become common onboard trains, as they clearly indicate to passengers where they are and where they are headed. I found this example onboard a Koltsevaya Line (line 5) train that encircles central Moscow.
So far these screen are only seen onboard the type 81-740/741 Rusich (Русич) trains, constructed from 2002 onbards.
Type 81-740/741 Rusich (Русич) trains are also used on other Moscow Metro lines, such as the above ground Filyovskaya Line (line 4), but without the dynamic next station displays.
