BR Class 20 Enginespec - For 2004 & 2006. A new enginespec to improve performance in AI/DCC mode. At the same time the CAB performance has been set up using accurate tractive effort data and adhesion values.
NOTE: this enginespec will cause locos that use it to accelerate and brake very slowly under AI/DCC mode in TC3 and TS2009. Please see TC3/TS2009 version of this enginespec.
