its air conditioning arrangements), and its aesthetic appeal. Railway journalist Richard Clinnick observed several minor shortcomings of the interior, such as the somewhat cramped seating arrangement and the lack of securing straps at the baby changing facility, but positively reviewed the overall package. In September 2010, it was reported that several passengers were concerned by the presence of a 'wobbling' motion that occurred within some tunnel sections; the phenomenon was described by Southeastern as non-dangerous, but all trains were fitted with dampers that prevent any recurrence of the issue. Operations and performance A full regular service commenced on 13 December 2009. Initial services included a half-hourly north Kent service to and from St Pancras, London, via Stratford, Ebbsfleet, Gravesend, Strood, Rochester, Chatham, Gillingham, Rainham, and Sittingbourne to Faversham, a half-hourly service to East Kent via Stratford, Ebbsfleet, Ashford with one train continuing to Margate via Canterbury West, Ramsgate and Broadstairs, with the other to Dover via Folkestone West and Folkestone Central. Seven million journeys were made in the first year of operation. The introduction of the trains was generally successful, with good reliability and passenger satisfaction figures. The new high-speed services also caused an increase in passenger numbers above that already being experienced on the Kent network. On introduction, timetabled journeys to London from Ebbsfleet were reduced from 51 to 18 minutes, whilst trains using the entire length of High Speed 1 (starting in Ashford) had timetabled journeys reduced by around 45 minutes. However, the service has been criticised as being of limited use to many London commuters because trains terminate at St Pancras. Additionally, the change in service patterns to accommodate high-speed trains resulted in some non-high-speed services in Kent becoming slower. In May 2011, a limited service from Maidstone West via and started, followed in September 2011 by a limited service from Sandwich via Deal to London St Pancras (partially subsidised by Kent County Council). In 2013, four years after the service started, total passenger numbers were ten million and punctuality was 92.6% (compared to 90.1% nationwide). Design The 400 Series Mini Shinkansen and Hitachi's A Train design form the basis of the Class 395 design. From the 400 Series the class inherits the same six-car 20-metre carriage with doors at one-third and two-thirds along the carriage. Both types of train are designed for operations at high speed on newly built lines, as well as at lower speed
