a switch engine to handle cars to and from the platform. By the new plan, the train icing platform was made about twice as long as the old, and the location moved to the east, providing train icing tracks on each side of the platform, connected at each end with main tracks, which make it possible to handle the trains direct to the icing platform with the road engines.

The facilities lie north and south and consist of a cross-bar double chain, inclined elevating conveyor, a gravity ice slide across the tracks supported upon a double Howe truss bridge, an elevated ice crusher house, salt storage and handling facilities, a high icing platform, part of which is double decked and having car icing tracks on each side, and platform ice conveyors. This installation, which handles 8,260 tons of ice per year, does not have an ice storage house, as the ice is brought direct from the plant of the manufacturer to the platform, by the conveyors, as needed.

The cake icing platform, which is 13 ft. 3 in. above the rail, 12 ft. wide and 1,652 ft. long, with icing tracks on each side, is of yellow pine lumber construction. The platform, also the roof over it, are supported on 8 in. by 8 in. posts on concrete footings. These posts are spaced 14 ft. apart, and are braced both ways below the platform, with 3 in. by 3 in. plank. The 2-in. plank floor is supported on 3 in. by 10 in. joists, spaced 16 in. apart, which in turn are carried on girders of two pieces of 4 in. by 16 in. timbers, set into the side of the posts. The roof over the platform is ready roofing on 1-in. D & Msheeting, which is supported by 2 in. by 6 in. joists, 20 in. apart, on 2 in. by 10 in. girders, set into the outside face of the posts.

A conveyor located on its center line and extending practically the entire length of the platform, allows cars on either side to be iced. This conveyor is divided into two equal parts with operating motors and machinery located midway between the ends of the platform. It is reversible, so the ice may be conveyed continuously in either direction.

At the north end and under the platform is a salt storage house on a concrete foundation, 42 ft. long and the same width as the platform. This house contains a storage bin 28 ft. by 11 ft. 6 in. and a working space 14 ft. by 11 ft. 6 in. The salt bin has a capacity of 50 tons, and is filled by hand from cars at the side of the bin, through wooden doors hinged at

the top.

The salt house is made of 3 in. by 10 in. studs, spaced 16 in. apart and lined inside with 2 in. D & M plank. The outside is covered with drop siding. The floor is made up of 2 in. D & M plank laid on 10 in, by 4 in. strips spaced 16 in. apart, over a subfloor of 2 in. D & M plank on a 3 in, by 10 in. floor, with the joists spaced 16 in. apart. The ceiling joists are 2 in. by 6 in., spaced 16 in. apart; over them are laid 1 in. D & M roof boards, covered with ready roofing. The salt is shoveled by hand from the storage bin into an elevator hopper, in one corner of the working space. The elevator, which is an electric driven chain bucket type, elevates the salt to a two-ton bin above the crusher house floor level, or about 28 ft. above the top of rail.

The ice crusher room is 11 ft. 6 in. wide and 42 ft. long with a 9-ft. ceiling at the low point. The construction of this room is the same as of the icing platform as to joists and girders, but the floor is made up of two layers of 2 in. D & M plank with one layer of ready roofing paper between. The floor pitches to the west, on which side are three floor drains connected to a drain pipe which discharges the water upon the ground below.

The walls of this room are made of 2 in. by 6 in. studs, spaced 24 in. apart with 1-in. D & Msheeting on each side, the outside of the wall

being finished with siding with one layer of tarred felt between the sheeting and the siding. The space between the wall studding is filled with burnt granulated cork from the floor to the ceiling. All of the windows have double sash and the doors are insulated cold storage doors, and were manufactured by the Stevenson Cold Storage Door Company. The ceiling is made up of two layers of 1-in. D & M boards with one layer of tarred felt between, which are nailed direct to the roof joists. The roof joists are 2 in. by 8 in., spaced 20 in. apart, and are supported by a continuous plate which is carried on the wall studding. The roof boards are 1 in. D & M and are covered by ready roofing. The roof slopes to the west and has a 3-ft. overhang on the sides.

The space between the wall plate and the under side of the roof boards is left open and is covered with No. 20 galvanized wire with Y2-in. mesh This is for ventilation purposes and air insulation against sun action.

Extending above the roof at the south end of the ice crusher room there is a penthouse 11 ft. 6 in. wide and 10 ft. long, with a 7-ft. ceiling, which contains the machinery for the salt elevator. In the southeast

corner of the crushing room, under this penthouse, is an elevated salt storage bin of two-ton capacity. At the bottom of this bin, and five feet above the upper platform level, there is a spout with control gate for filling push carts with salt.

To the south of the crusher room is a platform 84 ft. long and 21 ft. 3 in. above top of rail, approximately the same elevation as the low point of the crusher room floor. This platform, which is of the same construction and width as the cake-icing platform below, is used for icing cars with crushed ice, carts being the means of handling same. Just
