POST OFFICE SERVICE
RAILWAY MAIL SERVICE - A Brief History
At least three decades before the Pony Express galloped into postal history, the "Iron Horse" made a formal appearance. The Post Office Department recognized the value of this new mode of transportation for mail as early as November 30, 1832, when the stage contractors on a route from Philadelphia to Lancaster, Pennsylvania, were granted an allowance of $400 per year "for carrying the mail on the railroad as far as West Chester (30 miles) from December 5, 1832."
After passage of the Act of July 7, 1838, designating all railroads in the United States as post routes, mail service by railroad increased rapidly.
At this time, mail was sorted in distributing post offices. The only mail sent to the agents on the railroad lines was that intended for dispatch to offices along each route. The route agents opened the pouches from the local offices, separated the mail for other local points on the line for inclusion in the pouches for those offices, and sent the balance into the distributing post offices for further sorting.
Gradually, the clerks began to make up mail for connecting lines, as well as local offices, and the idea of distributing all transit mail on the cars slowly evolved.
By 1930, more than 10,000
trains were used to move the mail into every city, town, and village in the
United States. Following passage of the Transportation Act of 1958, mail
carrying passenger trains declined rapidly. By 1965, only 130 trains carried
mail; by 1970, the railroads carried virtually no First-Class Mail. On April
30, 1371, the Post Office Department terminated seven of the eight remaining
routes. The lone, surviving railway post office ran between New York and
Washington, D.C., and made its last run on June 30,1377. Information

Carrying the mail by rail was originally a very lucrative venture and railroads as well as trolley lines eventually all competed to win these government contracts. Another milestone was the establishment of the Railway Mail Service in 1864 which standardized a lot of the mail carrying.
Seeing that the alternative back then in the early days of mail carrying was horse and rider or horse and wagon over unpaved dirt roads, trails, paths or old wooden planked turnpikes, mail-via-rail proved to be a more efficient and quicker means of transporting the mail.
As the mail service handled by the railroads and trolley lines began to grow, special cars were constructed to not only carry the mail, but to be able to sort the mail by destination so that upon arrival at a terminal, the mail would be sorted and bagged and sent on its continued destination.

The railroads began to purchase cars from railroad car manufacturers designed specifically for this service. Such cars were referred to as Railway Post Office (RPO) cars and on the LIRR there were different types of cars for mail service.
The cars for which I have photographic record in my archive are of all steel construction and those are which will be depicted in this vignette.
Some of the steel cars were ½ mail car and ½ express car and the mail end would be stenciled “Railway Post Office” and the express end would be stenciled “Railway Express Agency” or whatever express company was in force at the time (Adams Express, American Railway Express, Railway Express Agency). The mail compartments on board were 30’ in length.
Some cars were built as baggage cars to which mail compartments were added by the LIRR itself over the years then said compartments were removed when they were no longer needed.
There were RPO cars in both MU (multiple unit) electric service and in steam/ diesel service.
The steam/diesel service cars which had compartments added bore the class of BM60: “B” meaning “Baggage” and “M” meaning “Mail” and the 60 being the length of the car in feet.
Other classes which were equipped with 30’ postal compartments were BM62, BM62A and BM62B.

BM62 car #7743 was specifically assigned to the New York and Patchogue Railway Post Office run, operating on MU trains west of Babylon and behind Rail Diesel Cars (BUDD RDCs) east of Babylon. This car was unique in that it had electric and steam heat as well as a small kerosene heater for when in service behind the RDCs.

Unlike the other RPO
cars depicted below, the platform-accessible mail slot is located in the
center of the car, slightly above and to the right of the road number as can

RPO cars in third rail, electric MU territory were classed MBM62 and MPBM54. The first “M” stood for “Motor” meaning they were electric powered units, used to pull the train with motorman in the cab. The “P” meant the car carried passengers, the “B” meant the car carried baggage, the second “M” meant the car carried mail and the number following was the length of the car in feet.
The MBM62 were RPO/REA cars:

The MPBM54 were RPO/Combine cars, meaning the car handled mail, baggage/express AND carried passengers.

Handling the mail was a serious business and mail handlers on board trains had to observe security precautions. Windows on the cars were barred, doors were locked and employees wore sidearms.

Mail could be dropped by individuals wishing to mail a letter into a RPO car while it was sitting at the station platform. A typical mail slot was installed in the side of the car near the door and it was of sufficient height to be reached by someone standing on the platform.
four images are close-ups of the images of the cars posted above to show the
location of the mail slot built into the side of the car to allow people
needing to mail a letter while at the station to drop it conveniently in the
side of the car, probably on the very train in which they will soon be
of mail were brought to and from the respective Post Offices and railroad
stations to be loaded on the train or taken back to the Post Office. My
father remembers the Postmaster at Holtsville meeting the train with the
mail bag in a wheelbarrow. The Post Office at that time was in an old
general store called Lydecker’s which used to

loading or manhandled off the car into some form of conveyance . . . . a
truck . . . a postal worker’s car trunk or, as in the case at my hometown
of Holtsville, the Postmaster’s trusty old wheelbarrow for the “trip”
back to Lydecker’s store.
most times mail was picked up “on the fly” meaning the train didn’t
stop. This was effected by a POD employee or, in some instances, a
designated railroad employee lugging the hefty mailbag to a trackside mail
crane. He climbed the ladder and hooked the top of the mailbag on the
upper arm and then yanked the lower arm down and hooked the bottom of the
mailbag to it, stretching the bag taught.

steel bar attached to the side door of the RPO car was swung from the
“out-of-service” position of straight down, to the “in-service”
position of straight out. The bar would lock in place and it’s
location across the car door also acted as a guardrail to keep the mail
handler from falling out of the moving train.

the bag was snagged, the momentum of the train and the resulting breeze kept
the bag wrapped around the steel bar until the mail handler would lug the
bag inside the train to be opened and sorted into various other destination
bags on board.
reverse operation, the mail bag, if on a non-stop train, would be tossed off
in the vicinity of the mail crane while the train was at speed and the
designated railroad employee would retrieve the bag, bring it into the
ticket office and await its pickup by one of the postal employees from the
local Post Office in town.
tossing of the bag from a moving train created a problem initially.
Sometimes the bags would hit the hard ground and bounce back up and go under
the wheels of the train where the bag would be run over, severed and the
mail strewn all over.
If you refer to the image above of the mail bag on the crane at Central Islip in the snowy, winter view, look at the base of the crane and beyond . . . you’ll see the slat fence to stop the mailbag from going under the train.
The photo was taken just after diesels took over the LIRR. I always wanted a picture of a train picking up mail but I had forgotten railway mail pick-up rule #1: What gets picked up also is detrained.
Anyhow, I felt an object go whizzing by my head just as I snapped the photo. It was the off-loaded bag and it missed me by inches. It appears in the photo just about at the coupling point of the engine and RPO car.
I was lucky--another few inches and my brain would have been scattered along the ROW and deservedly so.
Well, it was a lesson I would never forget! Info/Photo: Stephen Myers

hobby of collecting stamped “RPO” covers some of which are depicted

stood for “Railway Mail
According to fellow LIRR historian Art Huneke, each branch that
handled the mail was a separate contract between the LIRR and the US Post
Office Department.. . and, while all branches carried the mail, not all
branches sorted the mail, although most did.

territory: The cover would have been handled on a MU Motor RPO car as
shown above and operating on the LIRR’s Far Rockaway branch, a branch that
is all electrified. The postmark reads “N.Y. & Far Rock” and
was handled on train #1127 on November 22, 1940.
Mail service in steam/diesel territory lasted much longer until it eventually came to an end due to the convenience and cheaper carrying of mail by truck and because the mail contracts over the years became more of an inconvenience and less of a money-making proposition than they had been initially.
Some post offices were actually located in the LIRR depots themselves. The Plandome Post Office was part of the old Plandome depot along the Port Washington branch and the Mill Neck depot along the Oyster Bay branch had a post office structure constructed into the side of the existing depot building.
the Shinnecock Hills depot was once a station
stop along the LIRR’s Montauk branch east of
As an eastbound
MU electric train blocks the crossing at the Merrick station to make the
scheduled station stop on c. 04/04/1965+, two U.S. Post Office Department
mail trucks have backed up on the street, close to the head-end RPO / REA
car to off-load mail from the train for processing and sorting for delivery
at the local postal facility. The motorman is keeping an eye on the
postal workers, probably anxious to be underway to escape the taunts from
irritated drivers trying to get to work. Railway Post Office service
was to come to an end on the LIRR a few months later. (Dave Keller
The last train to carry mail on the Long Island Rail Road was train #37 running from Speonk to Jamaica on June 18, 1965, thus bringing to a close almost 130 years of U. S. Mail service on the L.I.R.R. January 18, 2015
