No one marches on Washington, and Hayes…

No one marches on Washington, and Hayes is peacefully inaugurated on March 2; points 1 and 2 do take effect.

As regards the first and most important point, Hayes had already announced his support for the restoration of "home rule", which involves troop removal, before the election.

It is also not unusual, nor unexpected, for a president, especially one so narrowly elected, to select a cabinet member favored by the other party.

As for points 3 and  4, if indeed there is any such firm agreement, they are never acted on.

In any case, whether by an informal deal or simply reassurances already in line with Hayes's announced plans, talks with Southern Democrats satisfy the worries of many and so prevent a Congressional filibuster that had threatened to extend resolution of the election dispute beyond Inauguration Day 1877.

Woodward (1951) argues for an economic interpretation, whereby railroad interest meeting secretly at the Wormley Hotel in Washington had forged a compromise with aid to Southern railroads as the sweetener. (Woodward, C. Vann (1951). Reunion and Reaction: The Compromise of 1877 and the End of Reconstruction. Oxford University Press.)

However, no serious effort will be made to fund a railroad or provide other federal aid.

An opposing interest group representing the Southern Pacific will successfully thwart Scott's Texas and Pacific scheme and ultimately run its own line to New Orleans.

Hayes’s inauguration marks, for practical purposes, the restoration of “home rule” for the South—i.e., that the North will no longer interfere in Southern elections to protect the blacks and that the Southern whites will again take control of their state governments.
