This pictures don't fit the full screen, you can use then for a single
track - and let Traffic to place other tracks on the screen too (in
case of smaller screen resolutions - 640*480, 800*600 - they are also
suitable for single track scenes). They are background-only pictures,
therefore there is no timetable line example for each picture. Mostly
you should place a trackbed picture before or below this pictures to
get a correct railway scene.
As Traffic is capable to use *.jpg pictures as background pictures, the
most of this pictures is in jpg format - for photos it is the better
choice against the *.gif format.
All the pictures are painted by Jana Kalousova - the daughter of Jindrich
Kalous. I have combined some of the original picture files in order
to get a more wide picture.
