Signal Book Ril 301 Communications No. 1 - Changes

In the communications no. 1, which will go into effect at of 12 December 2008, several changes have been introduced.

Eighteen years after the Reunification of Germany, the distinction between the ex-DB signal book (DS 301) and the ex-DR signalbook (DV 301) has been dropped. However, some differences still exist:

Some speed signal IDs (namely: Lf 4 and Lf 5) still have different aspects and different meanings in both operations areas
Some shunting signals still have different signal IDs in both areas, namely the "W" board

But some more things have been changed and unified:

At derailers, the signal Gsp 2 (derailer is off) which was previously used only in DR area has been defined as points signal and renamed to Wn 7. It will gradually be introduced in all of Germany, replacing the Sh 1 if used at a derailer.
The DR signals Zs 4 (direction indicator) , Zs 7 (counter-line indicator), and Zs 11 (caution signal) now have the same signal IDs Zs 2, Zs 6, Zs 7 all over Germany
