of proof that the addition will not yield a reasonable return, it is ordered to widen its bridge by inclusion of a pathway for pedestrians and a roadway for vehicles.[236]
Grade Crossings and Other Expenditures by Railroads.--When railroads are required to repair a viaduct under which they operate,[237] or to reconstruct a bridge or provide means for passing water for drainage through their embankment,[238] or to sprinkle that part of the street occupied by them,[239] their property is not taken without due process of law. But if an underground cattle-pass is to be constructed, not as a safety measure but as a means of sparing the farmer the inconvenience attendant upon the use of an existing and adequate grade crossing, collection of any part of the cost thereof from a railroad is a prohibited taking for private use.[240] As to grade crossing elimination, the rule is well established that the State may exact from railroads the whole, or such part, of the cost thereof as it deems appropriate, even though commercial highway users, who make no contribution whatsoever, benefit from such improvements. But, the power of the State in this respect is not unlimited. If its imposition is "arbitrary" and "unreasonable" it may be set aside; but to reach that conclusion, it may become necessary to consider certain relevant facts; e.g., whether a new highway on which an underpass is to be constructed is essential to the transportation needs of a community already well served by a crossing equipped with devices which are adequate for safety and convenience of a local traffic; whether the underpass is prescribed as part of a national system of federal aid highways for the furtherance of motor vehicle traffic, much of which is in direct competition with the railroad; whether the increase in such traffic will greatly decrease rail traffic and hence the revenue of the railroad; whether the amount of taxes paid by the railroads of the State, part of which is devoted to the upkeep of public highways used by motor carriers, is disproportionately higher than the amount paid by motor carriers.[241]
Compellable Services
The primary duty of a public utility being to serve on reasonable terms all those who desire the service it renders, it follows that a company cannot pick and choose and elect to serve only those portions of its territory which it finds most profitable, leaving the remainder to get along without the service which it alone is in a position to give. Compelling a gas company to continue serving specified cities as long as it continues to do business in other parts of the State entails therefore no unconstitutional deprivation.[242] Likewise a railway may be compelled to continue the service of a branch or part of a line although the operation involves a loss.[243] But even though a utility, as a condition of enjoyment of powers and privileges granted by the State, is under a continuing obligation to provide reasonably adequate service, and even though that obligation cannot be avoided merely because performance occasions financial loss, yet if a company is at liberty to surrender its franchise and discontinue operations, it cannot be compelled to continue at a loss.[244]
