Due to bandwidth constraints, only members of our affordably priced RVElite subscription service may view ultra high quality videos.
Ultra high quality videos are encoded at a higher video resolution (640x480, the size of this light gray box), are sampled at bitrates of 4000+k/sec, have no compression added, and may be viewed by our valued RVElite members in full-screen mode.
Remarks: Trains are slowing down before the tunnel cause of works in progress and accelerating inside of them.Here can be seen the twin tunnel ( one and only) at Attica region.
