History The Baureihe 420 is a light-weight commuter electric multiple unit developed for the S-Bahn networks in Germany and was originally commissioned by the Deutsche Bundesbahn for the Munich S-Bahn, Stuttgart S-Bahn and Frankfurt S-Bahn networks. It could seat 194 second class, 17 or 33 first class, depending on series. The pivot distance was 16.5 m (54 ft) in cab cars and 14 m (46 ft) in trailer, with a floor capacity of ca. 1 m. It ran at 15 kv, 16⅔ Hz, with a tractive effort speed of 72 km/h (20 m/s; 45 mph) and acceleration of 0.9 m/s 2 (3.0 ft/s 2 ) or 2.0 mph/s (3.2 km/(h s)). It was built from 1969 onwards in several series, later changing the construction from steel to aluminum, making the cars more lightweight and able to carry a greater payload. It has largely been replaced in said cities by its successor, the Class 423, but some units have been shipped to Stockholm and some have been transferred to the Rhine-Ruhr S-Bahn network. In Sweden the fifteen units received designation X420 serving on the Stockholm commuter rail, and were in service from 2001 until the arrival of the new X60-series in 2006-08. Additionally, in the Rhine-Main Area, many units of class 420 are still in use, especially on lines S8 and S9 of the S-Bahn Rhine-Main. Today all trains of this class have been repainted in the DB-typical "traffic red" (verkehrsrot). Unit 420 001 will be preserved at the DB Museum in Nuremberg. Two 420/421 units in Stuttgart were rebuilt by the ET 420 Plus project, adding air conditioning and passenger information displays to the trains among other things. The aim of this project was to demonstrate a less expensive alternative to new trains in order of keeping the S-Bahn fleet up to date. However, as the new long-term carrier contract with Stuttgart Region includes the acquisition of 83 new class 430 EMUs, all 420s will be withdrawn from service in Stuttgart by 2013. 3

Not everything in a simulation can be reproduced faithfully. It may be that if you know the vehicle personally or have even driven, a few things stand out that do not agree 100%. We apologize for this. The sound should be handled in accordance with an interpretation. EFX: The cab's soundscape is adapted for use with EFX functions. Please turn on the EFX in the option menu of RailWorks TS2013 for optimal sound reproduction. The function is software based and therefore available on any computer. 4
Driving The train set is fundamentally accelerated and decelerated with the throttle lever. Throttle and reverser are initially in neutral position. The train brake is applied, the pantograph is risen and the main power is activated. For the first pulling away move the lever into desired position and release the train brake completely. Combined Throttle and Brake Control To speed up and slow down the train use the throttle lever. With 10 power and 9 brake notches, it allows a well-measured and dynamic driving style, depending on the selected throttle position. In neutral position no power is switched and both brake cylinders are vented. During brake the brake is connected in addition to a pneumatic brake supplement to increase the brake action, depending on the speed and length of the train. Tip: In dense suburban train operations, always begin braking at about 600m (at 120km/h) before entering a station using braking notch 8. Note that different long trains also behave differently when brake. The max. speed of the train is 120 km/h. if the max. speed will be exceeded by more than 5 km/h and longer than 5 seconds, a warning tone will sound (only on activated PZB). After a further 5 seconds the emergency brake will be applied. The brake will be released automatically whenever the speed falls down below maximum and the throttle lever is moved in neutral position. 5
Indicators Pic. 1 Pic. 2 6
Operating Controls Pic. 3 Pic. 4 7
Off Position Interlock In some normal operational situations a reset of the controller is required: If the train brake will be applied or an disorder occurs the throttle lever will be blocked electronically. The lever now is inoperable until a certain condition is met: Throttle lever, train brake and hand brake wheel have to be set in off position. Only when those conditions are met, the travel switch can be used again. This prevents the engine getting any electric power in emergency situations or if any brakes are applied in order to avoid any damage to the train (see also Brake and Door Control). Brake System Note: Only use the train brake in case of an emergency, or parking the train. In normal operation, the train brake is not used. The electronic system controls the brakes themselves. Basically, the handle of the driving brake is described in the chapter Driving. Make sure to vent both brake cylinder before re-acceleration. This is achieved by moving the throttle lever in neutral position until the brake cylinders are completely vented. Also make sure, train brake and hand brake wheel are fully released. On gentle slopes you can use the hand brake wheel (left click and moving the mouse) to held the train in its position (only at standstill). In normal driving the train should be held with the service brake. SIFA and PZB SIFA Driver Vigilance SIFA is short for Sicherheitsfahrschaltung or Safety Driving Switch. The SIFA vigilance alerter is disabled at startup, but can be activated or deactivated by pressing Shift+7' (only at standstill). After activating the SIFA test alert sounds and the warning light comes on. Confirm the test alert by pressing 'Q', Joypad 'A' or by clicking at the warning symbol in the HUD screen. Every 30 seconds and if the train is moving, the SIFA warning lights up again and after another 2,5 seconds the alarm tone sounds. Now the alarm should be acknowledged within 2,5 seconds to avoid an emergency brake. After acknowledging the brake will be released and the ride can be continued (see also: Off Position Interlock). PZB PZB is short for Punktförmige Zugbeeinflussung, its function is similar to the UK AWS function The PZB is disabled at startup, but can be activated or deactivated by pressing Shift+8' (only at standstill). After activating the system initializes a short self-test. The system now is active for train type O. By pressing 'CTRL+8' it can be switched between the various train types (train type O, train type M and train type U). 8
Pic. 5 There are three cab controls associated with Befehl40 / Override, Frei / Release and Wachsam / Acknowledgee (see Pic. 3) When passing a distant signal set at warning, the signal must be acknowledged with the Acknowledge key ( Page Down or 'NumpadEnter') within 2.5 secondss of passing or the emergency brakes will be applied. Pic. 6 If it is required to pass a red signal, press and hold the Override key Del while passing the signal. Make sure that the train speed is below 40km/h. By passing the signal, the befehl40 light will show. After passing the Override key can be released. Pic. 7 If the restrictive monitoring has ended (1000 and 500 lights are off) then any speed monitoring can be cancelled using the Release key by pressing 'End'. 9
Destination Display The AddOn includes a controllable destination display, which can be switched through by using 0 and CTRL+0. Various destinations, that are used quite often, are already deposited. Individual variations are possible in principle. The corresponding text file for it can be found in the folder Scripts of the AddOn. You should only modify those in case you have special knowledge in that field. Additional Features The DB Class 420 AddOn has some special functions. In addition to the horn of the train there is another sound which can be activated by means of pressing B. The transparent sun visors, which are fitted in the driver s cabin, can be individually adjusted by a simple mouse click. In order to have a look at the passenger cabin there are two different camera views. In addition to the functions already described, there is a door animation as well when passengers leave or board the train. Refer to the illustrated instructions for additional information and functions. Cab and Desk Light The lights of the driver s cabin can be switched on and off by using L. Additionally the light of the driver s desk can be switched on and off by using SHIFT + L. Automatic Couplings The end carriages of the train are equipped with automatic Scharfenberg couplers. Therefore it is suggested to activate 'automatic coupling' in the games setting menu before starting to play because otherwise manual engagement would still be necessary. Like in reality it is not possible to make coupling maneuvers between a middle and an end carriage. That would only be possible by mechanic personnel in a train depot. Disorders General Information As a virtual driver of a railway engine it is easy to get into an unexpected situation where the locomotive brakes down right in the middle of the track. Apart from operating errors when SIFA and PZB are activated, some additional explanations with respect to fault rectifications can be found in the chapters Brake System and Driving as well as SIFA and PZB. Brake and Door Control Whilst stationary the brakes are always in use when doors are opened and therefore startingup is impossible. After closing the doors and when all of the brake units are released, the pressure of the brake cylinders automatically decreases and acceleration is possible. In case one engages while the doors are open or there is a change of the driver s cabin, it is possible to avoid releasing of the brakes after the doors had been closed. At the drivers' desk you will find the reset interlock button to solve this problem (see also Pic. 4). 10
Information for Scenario Developers Of course, the train can also be used as AI traffic. However, there are a few things you should consider: One complete unit always should contain A-, M- and B-Wagon (A, M, A, or B, M, B combinations are also possible, but not prototypical). Complete Units are already defined and can be selected within the Consist Menu. If a unit isn't placed by using the Consist Menu make sure the M-Wagon has the same orientation as the A-Wagon, in order to avoid the wrong pantograph would rise. The AddOn includes a dynamic train number system. In order to display train numbers prototypical Therefore prototypical numbers are already deposited. By placing a wagon into a scenario a random number will be created. To create a authentic numbering of a complete unit the numbers can be edited within the editor. Further the train target destination display can be modified by using the following syntax: ZZA-xx-xxxxxxx. Using 'ZZA-3g-4200337 e.g. would define the train 420 033-7 as S3 going towards Mammendorf. Restart the scenario to get the modifying displayed. If only the number itself has been modified it will be displayed immediately. When a task is created, which requires a coupling maneuver or changing the driver's cabin, it is advisable to inform the player on the related Brake and Door Control (see also: Disorders). 11
