Dik's own words:
Comments, corrections and additions are welcome; please send an
electronic mail message to me.
If you have additions for the timetables, I prefer to receive
photocopies, but contact me first by electronic mail so that I
do not receive duplicates of timetables I do have already (no,
I did not yet enter all I have; but will in due course).
Please tell me what you think about these pages.
Dik Winter.
