I actually suggested this TT from CGL-TEL for 17643. This will reduce time travel and need for overtakes en route between GDR-TEL.
Once 17643 reaches TEL at 02.00,
BZA 03.45 / 04.05
BVRT 06.10
RJY...
more... 08.10 / 08.15
COA 09.50.
It travels behind 12759, 12669/12967/12969, 12615, 17215, 18520. Hence no need for overtakes.
Travel time reduced by 90 minutes.
Is there a suggestion portal where I can post this for the authorities?
