We analyse the three-colour electromagnetically induced transparency for the D_1 transition in cold ^{87}Rb atoms. We report an enhancement of the electromagnetically induced emission of a drive field as an exclusive enhancement of the third- and fourth-rank components of the density matrix. Moreover, the gain experienced by the drive field is attributed to the influence of the quantum switching effect on the increased absorption of the probe field. The electromagnetically induced emission effect is employed to generate slow light Gaussian-wave trains with shape preserving. These soliton trains were not only generated in the drive channel as has been designated but also in the switch channel which reveals multiple-light storage phenomenon.
