A pack of four CSX ES40DC's, each with a different horn. (Right for horns) I know I already have 5284 and 5288 made but why not, am I right? I am also aware of 5288's horn changing but once again, WHY NOT. CSX ES40DC (1st Gen K5HL) CSX ES44DC (3rd Gen K5HL) CSX ES40DC 5284 (3rd Gen K5HLB) CSX ES40DC 5288 (1st Gen K5HLB)
