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 signal book (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

Signal Book Ril 301 Communications No. 4 - Changes

We are now (summer 2011) already at communications no. 4. Notable changes in the updates 2, 3, and 4 are:

Introduction of ETCS stop marker
Appearance of signals for spring-loaded points has changed (one light is omitted and an orange stripe was added).
These signals were previously called So 18 and used only in the ex-DR area, now they received the new IDs Ne 13 and may be used nationwide.
Lf 6 and Lf 7 speed signals are now irrelevant for tilting trains (as these have a built-in speed supervision), drivers may disregard these signals
