in OpenType format, which also expanded the font family to include italic fonts (resembling those of Gill Sans) in all weights. OpenType features include alternates, case forms, small caps (romans only), old style figure. Separate small caps (romans only) and old style figure faces were also released for each weight in TrueType and PostScript formats, for a total of fifteen typefaces. P22 Underground In 1997, London Transport Museum licensed the original Johnston typeface exclusively to P22 Type Foundry, available commercially, first under the name of Johnston Underground and then in an expanded version called Underground Pro. P22's design is not based on New Johnston, having principally the goal of digitising and expanding on the original Johnston designs. The full Underground Pro Set contains nineteen Pro OpenType fonts and 58 Basic OpenType fonts, covering extended Latin, Greek, Cyrillic character sets. Weights are expanded to six: Thin, Light, Book, Medium, Demi, Heavy. Underground, Underground CY, Underground GR support extended Latin, Cyrillic, Greek characters respectively. The Latin sub-family contains medium weight Titling fonts, which feature underscored and/or overscored Latin small letters. Pro fonts include extensive OpenType features, including eleven stylistic sets with stylistic alternates inspired by early signs, Johnston's calligraphy and draft designs for Johnston and geometric sans designs such as Futura. Following the lead of Johnston's original, P22 decided not to offer an italic. The original Johnston Underground digitisation included Regular, Bold, and Extras weights, with the Extra containing only ornamental symbols. Railway Sans An open-source interpretation of Johnston's original (regular weight) by Justin Howes and Greg Fleming. Including a number of alternate glyphs such as a Garamond-inspired W (used on old signs at West Brompton station), ligatures and a characteristic arrow design. Paddington A basic public domain digitisation by Stephen Moye, including italic, bold, and small caps designs. Usages Its use has included the Tube map (sometimes hand-lettered), nameplates and general station signing, as well as much of the printed material issued by the Underground Group and its successors; also by the nationalised British Road Services in the immediate post-war era. It was also used for wayfinding signs at the London 2012 Summer Olympics and Summer Paralympics, including venues outside London. It was also used for the signs that accompanied the parade of nations during the opening ceremony. It is also used in the overlays of the BBC TV show Sherlock. New Johnston is used for signage in the fictional Princeton–Plainsboro
