Here are two DART25s on the test track just before they went out to their owners. Both these trains are sporting the pantograph arc light, internal lighting and passengers.
Here is a short video of the Windowed DART on its first public run at the Bray Model Show.
Here are some videos
In the first two videos DART 10 (a DART25, the current livery) is running on the inner loop, with a CIE livery version on the second, and Guinness livery on the third loop. .
And a 1980’s CIE livery when first introduced
And a Guinness livery one.
Now the Guinness livery and CIE livery together- never seen before.
