1.1 The meanings of signals 1.1.1 The DB Signal Code The Signal Code (DS 301, applicable with amendments since 15 December 1959) for what was Deutsche Bundesbahn or DB contains: Railway Signalling Regulations (ESO) as statutory provisions and the ESO implementing regulations. Legal foundations Statutory provisions EBO ESO EVO GGVSE Additions by DB AG Signal Code DS 301 Instructions to implement the ESO (implementing regulations) Separate Local Regulations for operating control points and train crews from the EBA The Signal Code (DV 301) for the former Deutsche Reichsbahn or DR (in what was East Germany) entered into force on 1 October 1971. It has continued to be applicable since the Unification Treaty of 31 August 1990 despite extensions being made to the area governed by ESO. There are currently 3 valid variants of the Signal Code: a joint Signal Code, DS/DV 301 DS 301 for what was Deutsche Bundesbahn (DB) und DV 301 for what was Deutsche Reichsbahn (DR).

Layout of DS/DV 301: Following Section A (General) with details of area of application responsibilities and definitions of terms, signals are divided into groups by function in Section B.

1.2 Features of signals Since the very beginning of the railway age, signals have served as a means of communication and have been key to the safety of the railway. This is why it expressly states in Paragraph 6 ESO that: may only be used in the prescribed forms, colours and tonalities and for the envisaged purpose. Features of signals ESO lays down binding specifications for signals as regards: Form Colour Signal Ra 5 Order to halt in shunting Three short blasts in rapid succession Signal Sh 5 Horn or whistle signal Three short blasts several times in succession Tone Page 4 DB, Participant s Manual, Version 1.1
Paragraph 7 ESO points out that the description prevails whilst illustrations merely have explanatory status. Representation of signals in the Signal Code Signal designation Signal s meaning Signal description Please note that the designations for and meanings of signals in DS 301 and DV 301 are divergent in some cases.

1.3 Signal systems 1.3.1 Stop and distant signals Stop signals indicate whether the section of line ahead may be negotiated. Stop signals are used as: entry or home signals, exit or platform starting signals, mid-platform signals, block signals. Functions of signals Entry (home) signal - protects entry into a station from open line Mid-platform signal -protectssectionsof track within the station Exit (starting) signal -protectsmovement out of a station onto open line Page 6 DB, Participant s Manual, Version 1.1
Stop signals single-arm semaphore double-arm semaphore colour light signal with one or two lights Stop signals ensure a section of track can only be entered if it is clear of vehicles. Stop signals single-arm semaphore double-arm semaphore colour light signal with one or two lights DB, Participant s Manual, Version 1.1 Page 7
Distant/stop signalling system Rechtsheim station headway section = space interval distant signal main signal 250 metres 1,000 metres Owing to the comparatively long braking distances of trains it is necessary for drivers to receive advance indication of stop signals in order that they can adjust their mode of driving to prevailing circumstances (e.g. signal at danger) in good time. Extract from Germany s Railway Construction and Operating Regulations (EBO) Section 39 Train headways (3) The distance between two succeeding trains on railways with a max. permissible speed of more than 30 km/h must not be less than one block section; where there is only one track, this must not be occupied anywhere up to the next passing point by a train travelling in the opposite direction. The distant/stop signal system comprises: warning signs: generally at intervals of 75 m, 75 m and 100 m ahead of the distant signal the distant signal is identified by means of a board attached to its post; distance from stop signal depending on braking distance for section; generally 1,000 metres the stop signal the safety overlap. Page 8 DB, Participant s Manual, Version 1.1
Warning signs and distances between them from Fkorn to Astadt jctn Wald to Fkorn Warning signs take the form of a series of rectangular white boards with black stripes that rise diagonally to the right and decrease in number as the distant signal is approached. There are signs at intervals of 75 m, 75 m and 100 m ahead of the distant signal. Distances from distant to main signal: 400 m, 700 m or 1,000 m A triangle on top of the warning sign indicates that the distance between distant and stop signal is more than 5 % shorter than the braking distance for the section. Presignalling distance protection point Braking distance Protection point 1000m Braking distance jctn Wald 1000m Braking distance Braking distance Braking distance Braking distance In difficult sighting conditions, a repeater signal may be mounted between the distant and stop signals (for colour light signals only). It is different from the distant signal in that it is not equipped with warning signs and has an additional white light on the signal screen. DB, Participant s Manual, Version 1.1 Page 9

1.3.2 Hl signal system The former Deutsche Reichsbahn in what was East Germany developed the Hl signal system to augment its distant/stop signal system. This system is set out in Signal Code DV 301 as well as in the joint Signal Code. All Hl signals are proceed aspects. The Hp 0 signal is used as the stop position. Differing speeds to be adopted are signalled using three items of signalling information. The following Table provides an overview of the meanings of Hl signals. from Overview of Hl 1/Hl 12 colour light signals to V max V 100 km/h V 40/60 km/h Halt Hl 1 Hl 4 Hl 7 Hl 10 Vmax 100 40/60 Vmax 100 40/60 Hp 0 Hl 2 Hl 5 Hl 8 Hl 11 Vmax 100 40/60 Vmax 100 40/60 Hp 0 Vmax 100 60 40 Hl 3 Hl 6 Hl 9 Hl 12 a b a b a b a b Vmax 100 60 40 Hp 0 V/max. = max. permissible speed flashing light flashing light strip of light strip of light DB, Participant s Manual, Version 1.1 Page 11

1.3.3 Ks signal system (combination signal system) The principal reasons behind developing the Ks signal system were as follows: With commercial speeds steadily increasing, it was becoming more and more difficult for drivers to register the wealth of lights on and information provided by stop/distant signals. Harmonisation of the signal systems adopted by Deutsche Bundesbahn and the former DR. Recommendation by the International Union of Railways (UIC) to adopt straightforward and manageable signalling principles. Key features of Ks signals are: Signal Hp 0 is used as the stop aspect Ks signals display all proceed aspects with one signal light Ks signals can act as - stop signals or - distant signals or - both. Ks signals acting as stop and distant signals are identified by means of a sign depicting a yellow triangle on its head fitted to the signal post. They are additionally indicated by means of the standard AB 4 signalpost sign provided for in the Signal Code. Page 14 DB, Participant s Manual, Version 1.1

1.4 Positioning of signals are generally located to the right of or above the track to which they relate - though to the left in the case of wrong-side running. Exceptions are indicated in the Local Regulations supplementing DS/DV 408, in the digest of temporary speed restrictions, sections subject to special traffic regulation and other special points (La) or in notices of works in progress where engineering is involved. Fixed signals used for wrong-side running are located to the left of the relevant track. Permanent exceptions are indicated in the Local Regulations. Chequered board Signal Ne 4/So 2 The stop signal is not located directly to the right of or above the track The stop signal is located elsewhere than specified in the rules DB, Participant s Manual, Version 1.1 Page 21
