British Transport Police say at least 12 horses have been killed, after being hit by two trains at Milton on Wednesday evening.
Two trains travelling in opposite directions were involved in the incident at the Fen Road level crossing in Milton, Cambridgeshire.
It led to major travel disruption and a female passenger was taken to hospital with minor injuries.
The 5.01pm Stansted to Birmingham service collided with the animals at about 5.15pm on Wednesday evening, British Transport Police said.
Another train, travelling from Birmingham to Stansted, was also involved.
Sergeant David Barker said:
"We are very keen to find out who the horses belong to. At the moment it is not clear how many horses died in the incident, however, we believe that at least seven were killed.
I also want to know how the horses came to be on the tracks. If anyone has any information, which they think that could help us in our investigations please get in touch.''
The breeds of the horses, which are believed to have come from the fields in the Fen Road area, are unknown.
Cambridgeshire Police, the ambulance service and firefighters also attended the incident.
