Just announced by Athearn, another run of Frisco Gp38-2 locomotives. Four SLSF numbers will be offered with locomotive-specific features.; 406, 411, 476 and 478 available with and without SoundTraxx Tsunami 2 sound. Tsunami 2 sound means that the decoder will respond to changes in throttle and engine load to step up the notching of the prime mover automatically. You don't have to lock the locomotive speed, press a function button and then play with your DCC throttle to get those changes while being unable to change the locomotive speed as with another brand. See Athearn's website for more information: www.athearn.com Pre-order through July 28, 2017 with projected delivery late June 2018. For those tolerant of the BN patches, four numbers will be offered with locomotive-specific features; BN 2256, 2258, 2328, 2331.
