Bachmann Trains, in compliance with state and community guidelines in slowing the spread of COVID-19, will extend the closure of its offices, including shipping, parts, and service, until at least April 6, 2020. We thank you for your understanding and wish everyone good health at this time.
Not sure where (offices in Philadelphia? ) their main US location is, but would assume that (a) the Chinese manufacturing capability may be running injection molded parts for medical equipment, and (b) given the current circumstances, the offices in the US will be closed well past April 6, especially if I am correct about location.
