Model parameters

Notation of parameters and variables	Parameter description
$G = (N, A)$	Railway network
$N$	Set of technical stations in the network
$S$	Set of stations within the hub
$i, j, p, q, s$	$i, j, p, q, s \subset N$ ⁠, $s$ denotes a station within the hub where dispatching and receiving operations can be performed
$A$	Set of arcs (line sections) connecting two adjacent stations
$(i, j)$	Arc $(i, j)$ belongs to the set of arcs $A$
$g_{1 p q}$	Number of OD conventional train sets from $p$ to $q$ (trains/day)
$g_{2 p q}$	Number of OD EMU train sets from $p$ to $q$ (trains/day)
$C_{i j}$	Maximum line capacity of arc $(i, j)$ (trains/day)
$w_{s}$	Dispatching and receiving capacity of station $s$ (trains/day)
$T_{s 3}$	Stopping operation time of conventional trains (seconds/train)
$T_{s 4}$	Stopping operation time of EMU trains (seconds/train)
$T_{s 5}$	Standard running time on hub arcs (seconds/train)
