Sherman Hill needs UP's Heritage Fleet, and Horseshoe Curve needs NS's heritage fleet. Here are my suggestions for both heritage fleets. Some of UP's Heritage Fleet (Challenger #3985, DDA40X #6936, and UP 2-10-2 #5511) are being sold to the RRHMA. -Pack 1: UP Heritage SD70ACes: -SP/UP #1996 -C&NW/UP #1995 -D&RGW/UP #1989 -MKT/UP #1988 -WP/UP #1983 -MP/UP #1982 -Pack 2: UP Steam Locos: -Big Boy #4014 -FEF3 #844 -Challenger #3985 -Pack 3: Other UP locos: -DDA40X #6936 -"Spirit of the UP" #1943 -UP #1111 -UP E9 A-B-A set A fourth pack should include the full UP Heritage Fleet passenger consist as well. Now, on to Norfolk Southern. NS has a large fleet of heritage units (21 in all). Most are SD70ACes or ES44ACs, but NS does have an ex-Erie Lackawanna SD45-2 #1700. Here is the list of locos for the NS Heritage Packs: -Pack 4: NS Heritage ES44ACs: -Central of Georgia #8101 -Conrail #8098 -Lehigh Valley #8104 -Interstate Railroad #8105 -Monongahela #8025 -NKP #8100 -N&W #8103 -NS (Original) #8114 -PRR #8102 -Southern #8099 -Pack 5: NS Heritage SD70ACes: -CNJ #1071 -DL&W #1074 -Erie #1068 -Illinois Terminal #1072 -NYC #1066 -Penn Central #1073 -Reading #1067 -Savannah & Atlanta #1065 -Virginian #1069 -Wabash #1070 -Pack 6: Other NS engines: -EL SD45-2 #1700 -Southern GP59 #4610 (no longer in this livery, but it should be included) -N&W 611 -Southern RR #4501 -Southern RR #630
