BNSF 1778 is just one of BNSF's many SD40-2's. Designed and built by EMD beginning in 1972, the SD40-2 was built as an improvement over previous EMD locomotives, featuring updated electronics. It competed against models from both GE and Alco, and was so successful that it set a new benchmark for the industry. It featured six axles and the EMD 16-645E3 prime mover output 3,000 HP. Though there were more powerful locomotives available at the time, the SD40-2 was immensely popular and remains one of the most used locomotives nearly 50 years later.
BNSF 1778 started life as BN 7033, built in 1978. It remained in BN colors until sometime after the merger, when it was painted into BNSF's "Heritage 1" scheme. Around 2009 the number was changed to 1778 when the new ES44C4's were placed in the 7000 series.
Around 2013 the locomotive went into the shops for a rehaul and upgrades. Air conditioners were added to the cab roof, and communications and electronics were upgraded. It was at this point that 1778 received a shiny new paint job in BNSF's "Heritage 3" scheme.
I captured this locomotive servicing industries in my hometown in 2016, and the paint still had much of its original shine. The underframe had gathered a decent amount of dust, as had the roof and walks, but the hood and nose were still very glossy.
The model started life as a Kato SD40-2. I stripped the paint, and removed all of the clunky details. I milled the frame down and took everything out of the fuel tank. Frame rails were build with styrene, the underframe, trucks, fuel tank and pilots were fully detailed. The stanchions were all drilled individually and new handrails bent from brass wire. Correct hood and cab details were added and fabricated as appropriate. The fans and all hood roof detail were replaced with Cannon parts. I primed, painted, and decaled the unit. Weathering was accomplished mainly with acrylics. The glossy hood was replicated with Future floor polish and the dull underframe was replicated with Dullcote.
The unit is controlled by Railpro and is fully battery powered. The battery resides in the fuel tank, and is plugged in under the dynamic brake hatch. It has a dual speaker set up and full LED lighting. It can run on battery power for 4-6 hours before needing a recharge.
