Some of the changes I made were the addition of 2 mini wireless video cams as the station is located under an N scale train layout and can only be viewed by peeking under the table. The 2 video cams allow for an easy view on my TV and you get a closer view of the action. The first cam is an angled frontal view of the station. The second cam captures the view at the track and edge of the platform with a figure waving. The still pictures show the station as it looks today with the addition of a signal as you can see in one of the photos. The video was taken before I added the signal.
By the way all these video cams can be changed from station to station by remote control. I have a total of 4 video cams to choose from. Cam #1 is a generic station, cam #2 is 14th street station, cams 3 and 4 are of Grand Central as shown.
The still picture below is taken with my camera and not of the cam image. The other pictures are taken of my TV screen showing the cam images.
