N157NS

The airframe bearing tail number N157NS is a Bombardier CL-600-2B16 Challenger 605 built in 2010, serial 5859, and manufactured by Bombardier Inc. The certificate and registry list the owner as NORFOLK SOUTHERN RAILWAY CO, a corporation based in Atlanta, GA, US, which indicates corporate non-airline use and a likely dedicated company flight department/operator connection. The aircraft is registered in the US, and public records note the certificated seating capacity of 22 even though typical executive interiors on this airframe differ from that full layout. No additional transfers or notable registry actions beyond the current corporate ownership are published in the supplied data.

This specific Challenger 605 is typically configured in a two-cabin executive layout; the FAA record lists 22 seats certificated but the airframe commonly carries a 9–12 passenger executive fit for corporate missions. Avionics are listed as Rockwell Collins Pro Line with the note that Challenger 605s commonly carry the Pro Line 21 suite, supporting modern cockpit capabilities for mixed corporate and ferry operations. With a long-range capability of 3,732 nm and a high cruise of 470 kts, the aircraft is suited to transcontinental and transborder flights for corporate personnel of NORFOLK SOUTHERN RAILWAY CO operating from their Atlanta base. Maintenance considerations for this individual airframe follow typical Challenger 605 schedules for CF34-3B powerplants and Pro Line avionics support.

The Bombardier CL-600-2B16 Challenger 605 occupies the super-midsize executive jet niche, offering extended range and higher passenger comfort than light jets while retaining access to many business airports. Competing models in the class include late-model Gulfstream G150/G280 derivatives and large-cabin offerings from Dassault and Embraer; the Challenger 605’s strengths are cabin volume and transcontinental capability. For buyers and fleet managers, resale and maintenance considerations hinge on engine CF34 series support, Pro Line avionics upgrades or serviceability, and interior configuration differences—here the contrast between a certificated 22-seat record and the more typical 9–12 executive fit is a key factor in valuation and mission planning.
