Last Saturday, (March 3) at 12:25 PM I sent off a custom built, super-detailed O scale 2 rail B&O dining car model to its new owner.
USPS Express Mail, 2 day gauranteed delivery, insured, with return receipt from Tulsa OK to eastern PA. Cost was $ 75.45 with delivery promised by Tuesday, March 5 at 3:00 PM. The box was 31" long, 7 1/2" high, 9 1/2 " wide and weighed 8 lbs 10 oz. Having the tracking number, I monitored the progress of its 1,300 mile or so trip.
The local PO sent it to regional sorting by 6:57 pm that evening. It left the sorting facility by 8:31 PM on March 3 and arrived in Philadelphia at 3:10 AM March 5th, a bit over 30 hours.
The Philadelphia sorting facilty sent it to the SE Pennsylvania sorting facility at 9:50 PM that evening, some 17 1/2 hours later. About 8 hours later at 5:50 AM the next morning (March 6) it arrived at the local PO for delivery.
It went on the delivery route at 7:25 AM. A delivery attempt was made at 10:08 AM but no one was home to sign for it so a notice was left. At 4:15 PM the package was signed for by the recipient, perhaps at the local PO.
I took three days instead of two for it to reach that person but I'm happy to have been able to track it so precisely up to the point of delivery. I still need to hear from him as to how well this model traveled.
