PROTO 2000 ITEM # 21618 AN ALCO PA WITH A PROTO 2000 ALCO PB LOCOMOTIVE A-B SET. DECORATED FOR THE NEW YORK CENTRAL UNITS # 4201A AND 4301B IN NEW YORK CENTRAL'S ELEGANT 2 TONE GRAY LIGHTNING STRIPE PAINT SCHEME. THE DETAILS REFER ONLY TO THE "A" UNIT AS THE "B" UNIT IS A DUMMY WITH NICKEL SILVER WHEELS IN DUMMT TRUCKS WITH SPRUNG KNUCKLE COUPLERS ON BOTH UNITS.THESE UNITS GET SLOWER WITH AGE DUE TO LACK OF LUBRICATION AND GREASE THAT DRIES OUT AND HARDENS LIKE GLUE . I RESOLVE THE ISSUE BY DISASSEMBLING THE ENTIRE UNIT, INCLUDING THE WEIGHT, THEN CLEANING AND LUBRICATING EVERY MOVING PART IN THE DRIVE. WHILE I'M IN THERE, I PAINT THE CAB INTERIOR & SEATS IN PROTOTYPICAL COLORS AND HAND PAINT THE CREW FIGURES IN COLORS YOU CAN SEE THROUGH THE WINDOW GLAZING. I REPLACE THE STANDARD INCANDESCENT LIGHT WITH A NEW LED OF WARM WHITE COLOR (2700 K). THEN I ISOLATE THE MOTOR AND INSTALL AN MRC 1922 DUAL MODE DECODER WITH INTEGRATED 1 INCH SPEAKER. THESE DECODERS ACTUALLY SOUND PRETTY GOOD AND ARE THE ONLY MRC DECODER I WOULD BUY.  THERE ARE 1 OR 2 LOOSE GRAB IRONS ON THIS UNIT, BUT NONE ARE MISSING. AFTER REASSEMBLY, I PROGRAM THE ADDRESS TO THE ENGINE NUMBER. LOOK CLOSELY AT THE PICTURES. THEY ARE PART OF THE DESCRIPTION. IT'S UP TO YOU TO JUDGE THE OVERALL CONDITION. ORIGINAL BOX HAS BEEN MODIFIED TO ACCEPT BOTH UNITS FOR SHIPPING AND STORAGE                                                                       COUNTRY OF ORIGIN: CHINA
