but delays mounted. A lawsuit settled by the MBTA in 2006 required changes to how accessibility renovations were designed. Previously undocumented utilities delayed excavation, and keeping the station open during construction presented difficulties. Two sets of stairs had to be kept open during the baseball season, which was prolonged when the Red Sox went to the playoffs in 2005, 2006, 2008, and 2009. The metal frame of the shelter was erected in 2006, but the fasteners for the glass had to be redesigned, delaying progress by several months. By November 2007, the project was projected to be completed in late 2008 – almost two years late – with the cost increased to $32 million. The station ultimately became accessible in January 2010. The total cost was $50.6 million; the original base contract had increased from $22.7 million to $40.7 million, almost entirely because of change orders for which the MBTA was at fault. Art panels featuring Red Sox players on station signs were unveiled at a ribbon-cutting ceremony on April 22, 2010. Station layout Kenmore station has four tracks serving two island platforms; the northern platform serves outbound passengers on all lines, while the other island platform serves all inbound trains. The B branch uses the inner tracks, while the C and D branches use the outer tracks. West of the station, the B branch crosses the C/D branches at a flying junction. The C and D branches split at a flat junction (Beacon Junction) further to the southwest. The Kenmore Loop connects the outer tracks, allowing inbound C and D trains to reverse direction without entering the main subway. The fare mezzanine is located over the middle of the platforms, with stairs and escalators from the platforms. Passageways lead to the exits on the north and south sides of Kenmore Square. An escalator and stairs lead to the busway, which is in the middle of the square. One elevator connects the south sidewalk to the fare mezzanine level, another connects the fare lobby to the outbound platform, and a third connects the busway to the inbound platform via the fare lobby. Bus connections As the last station in the subway before it splits into surface lines, Kenmore is a terminal for several MBTA bus routes: : Harbor Point–Kenmore station : –Kenmore or : –Kenmore station : –Kenmore station : Chestnut Hill–Kenmore station : Brighton–Kenmore station The station is also
