The Post's three business travelers to New York {Business, Dec. 6} overlooked the best method of all: Amtrak by overnight sleeper. It is much more convenient and certainly less hectic than racing around town in the early morning hours.

One can board beginning at 9:30 p.m. at Union Station. The train leaves at 10:30 p.m., with a stop at New Carrollton a few minutes later, before arriving in New York at 2:38 a.m. However, one may remain in the roomettes until 8 a.m. These must be reserved in advance.

The evening before a recent 9 a.m. meeting at Lincoln Center, I left my White Oak apartment at about 9:30 p.m., drove leisurely to the New Carrollton Station in less than half an hour, parked easily in the indoor parking lot, walked the short distance to the terminal and waited for the train.

When it arrived, the porter directed me to my roomette. A few minutes after we departed, he appeared again with a small complimentary bottle of wine and a plastic goblet, showed me where to hang my coat, explained how the bed folded down over the sink and toilet (no real problem unless you are more than about six feet tall) and asked what time I wished to be awakened and to have my complimentary breakfast. In the roomette was a plastic-wrapped tray with the usual nuts, sandwich and so on.

In the morning, I was awakened at the requested time, and a few minutes later the porter brought my breakfast of juice, coffee and muffins. I remained in the compartment until about 7:30 a.m., left Penn Station for a second breakfast and then took the bus uptown. Aside from the host, I was first to arrive for the meeting.
