$801,199 (5 Optional 1-Year Hardware Warranties)) to design, furnish and deliver an upgraded signal system
for LIRR’s Babylon to Patchogue segment of the LIRR Montauk Branch.
Following evaluations, the TEC held multiple discussions with Hitachi to discuss technical clarifications and to
confirm Hitachi’s overall understanding of the project. Following the discussions, LIRR made clarifying
modifications to the scope of work consisting of changes to the PTC Integration, Fire Suppression,
Interlockings and Reduced Aspect Signal requirements
. Overall Hitachi demonstrated a thorough and
comprehensive understanding of the project and adequately responded to all of LIRR’s questions.
