Tobias Unsin was able to catch the recently delivered X4E-640. The image shows the colorful locomotive on 15.02.2017 pulling the DGS 43155 Köln Eifeltor - Verona (with ES64F4-030) in Vogl (DE).
Note that the livery of the 640 changed a little. The slogan 'Connected by rail' was removed from both fronts. The MRCE logo (left) and the painted number (right) got a new place.
Update: a new image:
