The Gladstone Branch had two RPO services each day. Westbound it was was on Train #405 (lv. Summit at 7:46 am arrive Gladstone 8:38). It dropped off at waiting post masters who arrived at the trains in their cars. Stops were New Providence, Murray Hill, Berkeley Heights, Gillette, Stirling, Millington, Basking Ridge, Bernardsville, Far Hills, Peapack, and Gladstone. I'm not sure if there was a drop off at Lyons for Liberty Corners. I think that community was served out of Basking Ridge with RFD service (I might be wrong on that). There was no eastbound morning pick up. To my memory this was a combi MU car at the west end of the train.
During the day a westbound car trailed one of the trains. This was a full baggage car in full DL&W colors. It was a four car set (two MU sets) pulling it. As I remember, it was Train #421 (leave Summit at 3:13 pm arrive Gladstone at 3:53). Eastbound, the car was trailed on a four car MU set on #426 (levaing Gladstone at 4:38 arriving Summit at 5:37, and it went on to Hoboken). There were never any passengers carried in one of the MU sets. I always assumed it was just for the double power to pull the car.
So there were two drop offs during the day and one end of the day pick up. I don't remember what Saturday service was like. I do remember going down to the post office twice a day. I used to write postal cards to all the roads with passenger service asking them for their current timetables. So, the two and three weeks after I sent these all out would result in our mail box getting quite filled. I still have this collection from about 1956 to 1961.
I remember the stopping of mail, but I don't remember what that date was. Something like Feburary of 1959 sticks in my head. I remember, because all the crews were saying how this would cause a lot of trains to be eliminated through filings at the Interstate Commerce Commission.
