Lego 7938 Passenger Train and 7939 Cargo Trains

Finally managed to get some time to get the 7938 and 7939 trains set up and got some photos.  Had a lot of fun trying to avoid crashing the trains - I controlled the cargo train and my 8 year old son controlled the passenger train.  We did have a few head on collisions!

Update: Found this YouTube video of the 7939 being assembled:
