Maximum grade is a function of three factors: the power of your locomotives, the weight of your locomotives, and the number and weight of the cars in your trains. According to the folks at AOPA, MEF on US sectionals is determined a bit differently (the main difference being the use of 200 feet rather than 328 feet, so it’s still essentially the same concept – highest terrain/obstacle plus a small fudge factor): A figure, shown in each quadrangle bounded by ticked graticule lines on aeronautical charts, which represents the height in thousands and hundreds of feet, above mean sea level, of the highest known natural or manmade feature in that quadrangle, plus suitable factors to allow for inaccuracy and incompleteness of the topographical heighting information.
