Aceasta lucrare trateaza problemele legate de consumurile energetice din transportul feroviar i implicaiile numarului mare de restricii i limitari de viteza din punct de vedere energetic i al timpilor de parcurs. O mare parte din costurile serviciilor de transport
feroviar, indiferent daca este vorba de trenurile de calatori sau de marfa, o constituie pretul energiei consumate. Lucrul mecanic necesar deplasarii vehiculelor pe calea de rulare depinde de o serie întreaga de factori tehnici i nu numai. Conducerea trenului pe o linie pe care sunt prezente multiple limitari din punct de vedere a vitezei de deplasare, constituie o problema de conducere optimala rezolvabila cu ajutorul teoriilor de calcul variaional i de programare dinamica. Lucrarea de faa îi propune sa studieze impactul pe care le au restriciile i limitarile de viteza asupra consumurilor energetice i a duratelor de parcurs asupra trenurilor.

Abstract
Present paper deals with problems which are related to energy consumption and the involvement of the large number of
restrictions and speed-limits in the matter of energy and travel time. A large part of the costs of rail transport services, be it passenger or
goods trains is made up of the price of the consumed energy. Mechanic work necessary to move the vehicle on the roll-track depends on a
whole series of technical facts and not only. Driving the train on a track where multiple limitations are present from the point of view of
speed, constitutes a solvable problem of optimal drive with the help of variable calculation theories and dynamic programming. Present
paper is intended to study the impact restrictions and speed limits have on energy consumption and route length on trains.
