In the frame, or out of the frame?
Only in the frame named "trainRun (only R is capital)", eM02 automatically set to zero top margin.
It is better to set frame height to "280", and set "scrolling=no".
Sample:
<frameset rows="280,*">
<frame name="trainRun" src="eM02.html" scrolling=no>
<frame name="banana" src="banana">
</frameset>
* If you don't like banana, change it to another name.
When upper frame is not active, you can't control the train with keyboard.
