Canadian National No. 7470 is a O-18a class 0-6-0 "Switcher" type steam locomotive that currently works on the Conway Scenic Railroad in North Conway, New Hampshire. 7470 was built by the Grand Trunk Railway Point St. Charles Shops at Montreal, Quebec in June 1921. The Grand Trunk classified the switcher as F9 Class and numbered it as Grand Trunk Railway No. 1795. It soon became and renumbered as Canadian National No. 7470 when the Canadian National Railway absorbed the Grand Trunk in 1923, they reclassified it as a Class 0-18-a.
7470 was originally spared scrapping, until it was saved by being sold to the Canada Dominion Sugar, where it spent some additional years as a switcher. Later, in May 1963, it was purchased by the Ontario government for a transportation museum in Canada, but that never came to fruition.
7470 was acquired in 1968 by Dwight Smith, and in 1974 joined the Conway Scenic Railroad and renumbered as No. 47. It was renumbered back to No. 7470 in the mid 1980's. Today, No. 7470 is used primarily to power the Conway-bound Valley Trains during the autumn seasons, as well as special excursions such as Steam in the Snow. It has also pulled the Notch Train on special occasions, recently as of 2011.
No. 7470 made its last run on January 15, 2015 of its Steam in the Snow event and was out of service from 2015 to 2019 for its 15-year major federally mandated inspection and overhaul. No. 7470 returned to active service again on June 1, 2019 and made its first test runs under its own power for the first time since January 2015.

The ESU Full Throttle Steam files now include a few new logic features for added operational realism while still leaving you in control of HOW YOU wish to run your locomotive.
Heavy Load: F9 by default.
Similar to the “Drive Hold” button on the Full Throttle Diesel files “Heavy Load” allows you to adjust the “Steam Cut Off Valve” at any speed allowing for a fierce full chuff or drifting with snifters and rod clanks. Heavy load can also act as an offset allowing speed adjustments when engaged if desired.
Coast: F4 by default.
Opposite of “Heavy Load” Coast allows for a negative offset allow drifting sounds of Rods and snifter valves at any speed. You again have the option to hold the speed to adjust the speed with this offset active. Even allowing for an increase of speed with no chuffs as if drifting downhill.
Independent brake: F10 by default
Identical to the Full Throttle Diesel files. This allows for the locomotive to stop more quickly than its regular momentum would normally carry it. This one is pretty self-explanatory – just press the brake and come to a stop! For additional options there are 3 Braking rates that can be set up for user preference.
Articulation: Sound Slot 2
By adding Sound Slot 2 to the F8 Function Mapping and enabling the "Secondary Trigger" (CV250) you can add a second set of drivers making any ESU Steam File articulated.
Function Mappable Air Horn: F21 by default
Sound Slot 21.
Many Steam locomotives had a single chime airhorn equipped. Those modelling SP, MILW, and others can now have this feature and put it where they would like in the function mapping in addition to the whistle.
