Hi, I just received some Original Reading Railroad papers & books.
One of the items is a Safety Letter from September 1954. In the newsletter they mention coupling speeds of cars.
From the Newsletter: Reading System Sept. 1954:
Accurate judgment of coupling speeds.....You should ALWAYS keep coupling speeds at UNDER 4 MPH.
To judge the speed of your train:
Sight the "front end" of any car body against a telegraph pole or other fixed point CLOSE to the right of way. Note the seconds the car takes to pass the object in seconds.. (1001...1002...etc..)
refer to the chart below
Seconds for
car to pass
object -------- MPH
1 -------------- 28
2 -------------- 14
3 -------------- 9.3
4 --------------- 7
5 -------------- 5.6
6 -------------- 4.7
7 --------------- 4
8 -------------- 3.5
9 -------------- 3.1
10 ------------- 2.8
11 ------------- 2.5
12 ------------- 2.3
13 ------------- 2.15
14 -------------- 2
Yes....I tried this in G and the chart seems to be right! 7 seconds is a Perfect coupling speed
But I had to "Scale it down" to 2 - 2.5 Sec. for 1:20
Please let me know if it works in other scales
