Network Rail blamed delays at Lincoln Central Station and barriers across the city on October 21 and 22 on cable thieves.
Copper cables were cut by alleged vandals near Sincil Bank on Thursday morning, in an attempt to steal them, National Rail says.
Trains had to be manually signed, taking much longer than usual for many services to go in and out of Lincoln for several hours.
Some long freight trains even stopped in the middle of Lincoln while barriers were down on Thursday morning (pictured).
Network Rail says it has fixed the problem, and that trains have been running normally since 11.30am on Friday.
This is the second time in a month Lincoln has been affected by cable thieves.
On October 8 train services between Lincoln, Nottingham and Leicester have been disrupted due to theft of cabling in the Newark area.
