I guess slicing is not allowed in constraints, such as

forall (a in Network: a.block_in!=TrainData[a.train_num].origin)
sum(<a.train_num,i,a.block_in,ti,a.time_from> in Network)Move[a.train_num,i,a.block_in,a.time_from,tj]-Move[a]>=0;


Why not? It seems it would make processing more efficient.

I don´t know if I got your example right, but I´ve realized that a decision variable can´t be used to index a vector of decision variables both in the constraints and in the objective function.
