the same as previously, with services from Hatton Cross to Heathrow split. Alternate trains run either to Terminal 4 (around the loop and back to Central London via Terminals 2 & 3), or direct to Terminals 2 & 3 and Terminal 5. Heathrow Terminals 2 & 3 has a double crossover immediately to the east which can be seen from the platform. This is used to allow trains to enter either platforms 1 or 2 heading westbound to terminate here. It is used for the last Heathrow service of the day Monday to Saturday and during times of service disruption. Also, a short distance to the west, are two further crossovers where the single track loop line from Terminal 4 rejoins the eastbound track from Terminal 5 to Terminals 2 & 3. The station has six escalators of which two operate from the platform to the ticket hall area and two operate in the opposite direction; the other two connect the ticket hall area to the surface. A mezzanine floor between the platform and ticket hall levels provide staff accommodation and facilities. British Transport Police maintain a presence at Heathrow. Until 2012, free transfer was not possible between terminals, in contrast to the Heathrow Express. In January 2012, free travel was introduced for Oyster card and contactless payment card holders between the Heathrow stations on the Piccadilly line. Journeys from Heathrow Terminals 2 & 3 or Heathrow Terminal 5 to Terminal 4 via the Piccadilly line require a change at Hatton Cross (this journey is free, despite Hatton Cross not being part of the free travel zone). As of March 2012, the station had undergone renovation works which featured an extended control room, all six escalators refurbished, a station enhancement and two Step Free Access lifts from the ticket hall (located near the bottom of the escalators from street level) to the platforms. Step-free access to street level will continue to be served by the two airport lifts from the Coach station.
