Hanborough is HND. Think it was incorrectly named Handborough for a time.
139 years, according to Wikipedia. It changed in 1992.
There are some other stations where not all of the letters in the CRS code appear in the station name (as shown on trackside signs).
Some other stations use "X" to represent the word "Cross":
- Hunts Cross (HNX)
- Kirby Cross (KBX)
- London Charing Cross (CHX)
- New Cross (NWX)
- New Cross Gate (NXG)
Some have a letter which would be part of the name on the sign if it was written in a different way:
- Heathrow Terminal 4 (HAF) (F for Four)
- Heathrow Terminal 5 (HWV) (V as a Roman numeral)
- St Johns (SAJ) (A from "Saint")
Some have a letter, or letters which matches the area (county, etc.), but where the signs don't include it:
- Adlington (Cheshire) (ADC)
- Ashford International (AFK) (in Kent)
- Bentley (South Yorkshire) (BYK)
- Bootle (Cumbria) (BOC)
- Clapham (Yorks) (CPY)
- Creswell (CWD) (in Derbyshire)
- Ebbsfleet International (EBD) (in Dartford BC)
- Garth (Bridgend) (GMG) (in Glamorgan)
Some have a letter (or letters) which reflects a town or suburb the signs don't mention:
- Birkenhead Hamilton Square (BKQ)
- Exhibition Centre (Glasgow) (EXG)
- James Street Liverpool (LVJ)
- London Road (Brighton) (LRB)
- Maesteg (Ewenny Road) (MEW)
- Meadowhall (MHS) (in Sheffield)
Some reflect a name the station used to have, or at least a name which was considered for the station:
- Bedford (BDM) (Midland Road)
- Eltham (ELW) (Well Hall)
- Harwich International (HPQ) (Parkeston Quay)
- Heysham Port (HHB) (Harbour)
- James Cook (JCH) (Hospital)
- Kirkby Stephen (KSW) (West)
- Mansfield (MFT) (Town)
- Queens Park (London) (QPW) (was West Kilburn)
I don't know if there's any significance to the last bit of the following:
- Anerley (ANZ)
- Heathrow Terminals 2 & 3 (HXX)
- Maghull North (MNS)
- Stow (SOI)
- Streethouse (SHC)
