Providing enough steam to power train heat and some air conditioning systems on postwar trains taxed the standard water supply of EMD F units set-up for passenger service, prompting EMD to rollout the new FP7 in 1949. Though outwardly similar, FP7s were actually four feet longer to accommodate bigger water tanks with a capacity of 950 US gallons. Standard passenger power into the Amtrak era and beyond (with some also handling freight chores), these WalthersProto replicas are fully assembled and ready for service with:

• New tooling matches the prototypes extended frame and body
• Available with ESU LokSound 5 Sound & DCC for DCC and DC layouts
• Railroad-specific details
• Limited edition - one-time run of these engine numbers
• Five-pole, skew-wound, high-torque, high-efficiency can motor
• Helical gears with 14:1 ratio for smooth, ultra-quiet running
• Easy multiple-unit operation
• Proto MAX(TM) metal knuckle couplers

 
Leading the Twin Cities Hiawatha from 1950 to 1971, the Milwaukee roster boasted 16 FP7-F7B-FP7 sets that easily nudged the century mark whenever schedules demanded!
 
As the Milwaukee assumed operation of Union Pacific Chicago-Omaha trains in late 1955 (and perfect for pool service with the WalthersProto 1960s City of Los Angeles - sold out at Walthers; see your dealer), yellow and gray became Milwaukee's standard colors well into the 1970s. Various standard appliances were also changed over time, including air horns, radio antennas, pilots and more, while unique Milwaukee touches including "barrel-style" spark arrestors, and sheet metal bug and snow deflectors were also installed. Based on updated units in service from 1955 to 1971 and beyond, these WalthersProto replicas are ideal for Twin Cities Hiawatha service and feature:

• Firecracker radio antenna
• Nathan S-2 air horn
• Lifting lugs on nose
• Cab-mounted bug & air horn snow deflectors
• Forward-facing barrel spark arrestors
• Roof-mounted oil cooler
• EMD round-corner winterization hatch
