Visiting Whitefield, Littleton, etc.

Does anyone know the most likely time to see a train on a visit to Whitefield? Does anything run in Littleton these days? I'll be spending a week or so in Sugar Hill, not so far away, in a couple weeks.
That's the New Hampshire and Vermont, right?

The Twin state railroad in VT. and the NHVT in NH. trackage is now silent still in place but no trains have turned a wheel from St Johnsbury east to Whitefield since CSF Acquisition Corp. the lessee of the line pulled up spikes and headed back to Florida. I think the State of NH. has rights to the NH. portion of the line and the State of VT is looking into purchase of the line from St. Johnsbury to the NH. side.
