About the Game The 4VEP Add\-On takes you back to the days of the classic ‘slam\-door’ commuter trains on the Woking\-Portsmouth Line\. The 4VEP \(‘Vestibule Electro Pneumatic’\), named the Class 423 under the British Rail TOPS classification system, was one of the ‘slam\-door’ electric multiple units that formed the backbone of rail passenger transport in southern England from the 1960s until after 2000\. EMU’s like the 4VEP were a part of daily life to hundreds of thousands of commuters, with the persistent slamming of their doors signalling the imminent departure of another busy service\. Each 4\-car set was powered by 750\-volt DC electricity supplied via a third rail, giving a top speed of 90mph\. Built by BREL at York, these classic EMUs served for almost 40 years, their high\-density seating layouts and performance proving adequate for their role until the introduction of the more modern ‘Dersiro’ units\. PLEASE NOTE: the 4VEP Add\-On requires the Portsmouth Direct Line Expansion Pack \(available separately\) to play\. Includes Class 423 ‘4VEP’ electric multiple unit in BR Blue/Grey and Network Southeast liveries\. Features accurate cab controls including notched throttle lever with Off, Shunt, Series, Parallel and Series notches and realistic dual\-mode braking system\. 3 free roam scenarios for the Portsmouth Direct Line 5 standard/career scenarios for the Portsmouth Direct Line PLEASE NOTE: the Portsmouth Direct Line Add\-On, available separately, is required to play these scenarios\) April Showers \(Standard & Career\) Network Southeast Last Train Home \(Standard & Career\) Network Southeast To the Rescue \(Standard\) BR Blue & Grey The Suits Express \(Standard & Career\) BR Blue & Grey Stoppin’ & Startin’ \(Standard & Career\) Network Southeast ## Game information - Type: dlc - Developer: Dovetail Games - Publisher: Dovetail Games \- Trains - Release date: May 17, 2012 - Coming soon: false - Free to play: false - Parent Steam app: 24010 - Genres: Simulation - Categories: Single\-player, Downloadable Content, Steam Achievements, Partial Controller Support, Steam Cloud, Steam Leaderboards, Family Sharing - Platforms: windows - Website: Not collected - Screenshots: https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_55e01050834b475c46c2a4625a33dec02be5e881\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_40652284452beb849b9c6c2a5131105624ff954e\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_d18164c6bd8acce39b8063fe73e4e28eb2fad7e1\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_371f1c68cbffd3a9d4af0c819bd004e998041a77\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_c3e1bb0d9282e87b4fbeef8a1379d513b13fc109\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_57fd86e80a230382b6ea61b5c3e98777c6864276\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_add80463780bad60314d8d49f8e561bc62416877\.1920x1080\.jpg?t=1734966494, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/65256/ss\_6078885555ff990fcfa7906450eb7548a2f163e2\.1920x1080\.jpg?t=1734966494 - Price: 899 minor units USD; discount 0% - Price country: US ## Observed metrics - Current players: Not collected - Steam review count: 14 - Steam positive reviews: 10 - Steam negative reviews: 4 - Steam positive percentage: 71.42857142857143% - Summer DB rating: No native votes Review filters: \{"language":"all","review\_type":"all","purchase\_type":"all","filter\_offtopic\_activity":0\} ## Player history [Seven-day chart data as Markdown](/api/v1/entities/8357cd41-859f-4759-8573-69f6fc88e3eb/player-metrics?days=7&format=markdown) · [JSON](/api/v1/entities/8357cd41-859f-4759-8573-69f6fc88e3eb/player-metrics?days=7) Chart values are hourly observed maxima.
