This weas termed a Grossangriff and the chances of finding out who might have done the deed are almost nil. For example, I have the following units from Luftflotte 3:
II/KG 76 9 ac 2000-0200 hrs
I/KG 77 7 ac 2210-0130 hrs
I/KG 27 26 ac 2030-2200 hrs
II/LG 1 11 ac 2022-2215 hrs
III/LG 1 8 ac 2041-2217 hrs
I/KG 27 16 ac 2205-2345 hrs
II/KG 27 11 ac 2045-2205 hrs
I/KG 51 8 ac 0100-0200 hrs
II/KG 51 7 ac 0150-0310 hrs
III/KG 51 3 ac 0305-0315 hrs
Stab & I/KG 55 8 ac 2105-2200 hrs
II/KG 55 19 ac 2147-2350 hrs
III/KG 55 7 ac 0010-0105 hrs
Noting your times, this would preclude I/KG 27 (first op), II/LG 1, II/KG 27, I/KG 51, II/KG 51, III/KG 51, III/KG 55. However, the only Geschwader that mentioned seeing bombs exploding near a 'central railway depot' was II/KG 55.
