First, the good news about the new Fall River-New Bedford commuter rail service, aka South Coast Rail: Banker & Tradesman and the Standard Times are reporting that Lafrance Hospitality wants to build a $25 million hotel near the recently opened commuter rail station in New Bedford. It’s considered among the first major development proposals tied to the new month-old train service. Expect more development proposals moving forward. And hopefully they’ll include lots of residential housing plans. … But here’s the bad news: The new rail service is already suffering from delays and cancellations, as the Herald News and Boston.com report.  … Sigh.  …  Well, they can’t blame antiquated equipment this time around. So what is to blame? A severe staffing shortage, T officials say.
