ELRMileages.search_conn(start_elr, start_em, end_elr, end_em)¶ Search for connection between two ELR-and-mileage pairs.
- Parameters
start_elr (str) – start ELR
start_em (pandas.DataFrame) – mileage file of the start ELR
end_elr (str) – end ELR
end_em (pandas.DataFrame) – mileage file of the end ELR
- Returns
connection (<end mileage of the start ELR>, <start mileage of the end ELR>)
- Return type
tuple
