===Free intra-terminal transfers===
Until 2012, free transfer was not possible between terminals via the Underground, unlike on 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 Terminal 5 to Terminal 4 via the Piccadilly line require a change at Hatton Cross; this journey is free.

[[File:Western Rail Approach to Heathrow.png|thumb|The proposed [[Western Rail Approach to Heathrow]]]]

[[Network Rail]] has put forward a proposal for a [[Western Rail Approach to Heathrow]], a short spur of track in tunnel which would run from a junction east of {{rws|Langley}} to Terminal 5 station. This would permit [[Great Western Main Line]] trains to run directly from {{rws|Slough}} and {{rws|Reading}} into Heathrow, without the need to change at Paddington. The proposal is currently at consultation stage and remains unconfirmed.<ref>{{cite web|title=Heathrow rail link -|url=https://www.networkrail.co.uk/our-railway-upgrade-plan/key-projects/heathrow-rail-link|website=Network Rail|access-date=12 July 2017}}</ref>

In addition to the above rail links, Terminal 5 station also has two safeguarded "heavy rail" platforms for use by a west-facing connection to the [[National Rail]] network. The south-leaning proposal would spur off the [[Waterloo to Reading Line]] west of [[Staines railway station]] (originally dubbed [[Heathrow Airtrack]], with a newer proposal named [[Heathrow Southern Railway]]). It proposes direct rail services to [[London Waterloo railway station|London Waterloo]], [[Reading railway station|Reading]], [[Woking railway station|Woking]], [[Guildford railway station|Guildford]] and [[Gatwick Airport railway station|Gatwick Airport]].<ref name="airtrack">{{cite web |url=http://www.heathrowairport.com/portal/page/Heathrow%5EGeneral%5EOur+business+and+community%5EHeathrow+transformation%5EHeathrow+AirTrack/100046e4daa55110VgnVCM10000036821c0a____/448c6a4c7f1b0010VgnVCM200000357e120a____/ |title=Heathrow Airtrack |publisher=BAA |access-date=6 January 2010}}</ref> Due to the cost of replacing three level crossings, one in a very urban part of [[Egham]], the proposals are currently unfunded.
