Pit line is just an open track with a provision for staff to walk below the coach for checking the under-slung equipment ( brake pipes, batteries, bogies etc). Any pit-line will be able to handle both LHB and ICF coaches. Camtech designed pit-lines are just pit-lines with proper drainage and some provisions for smoother maintenance.
To maintain LHB rakes, the coaching depot requires the corresponding spare parts, electrical and mechanical equipment and the necessary training to handle them.
