The last three I've watched go by, north and south, (Up and Down) (it's now 10:10AM) have been MP40 10 car sets. Perhaps today's service disruption has delayed changing in the shorter consists, I'll keep watching.
At 10.10am, depending on where your office is and provided that service is operating as normal, you should have seen all three of the trainsets - 268, leaving Mount Pleasant at 9am, and 269 and 271, leaving Union at 8.55am and 9.48am.
If they have decided to run shorter consists, which makes eminent sense, that flies in the face of others in these forums dissing the suggested idea some months back. It not only saves needless wear and tear, it saves fuel and uses the second lifetime of the refurbished F59s. I'll keep watching out my 18th floor window while working to see what shows later.
Cost savings is not what is purpose of this, and frankly the cost savings aren't huge in any case. The main driver is to try and get as many trains on the road, and by doing this they've been able to build two trains from one (with the addition of 2 more cab cars - which are currently plentiful).
Anyone have a link for this?
