#COVID19 transmission on a train:
This study quantified the risk of infection based on duration and proximity to an infected person.
"Overall attack rate of COVID-19 in train passengers with close contact with index patients was 0.32%"

TIME on train:
-Attack rate with 1-hour co-travel time is 0.25%, and with 7 hours 0.38%
PROXIMITY to case:
-Closer to index case = higher risk (shocker).
-3.5% attack rate if sitting next to case
-Attack rate drops significantly if >2 rows apart

Generalizability - trains are clearly not the same a planes in terms of air circulation, air flow patterns, hepa-filters etc.
While duration of exposure & proximity to an infected case are also important on planes, the overall risks are likely smaller.
