The sunlight makes a rare appearance between afternoon thunderstorms as Pan Am Railways "EDPO" works Lawrence Yard in Lawrence, MA. Their only snoot nose SD40-2 (ex-KCS) #606 leads an ex-QNS&L SD40-2 #3403 and an ex-CR/PC GP40 #313 as they pull down "Track 17 East" to make their set off and pickup.
