Can Anyone Tell Me The Maximum Haulage For These NSW Locomotives?

[alucardvamp]

I'm looking for the maximum tonnage that these classes of NSW Locomotives can pull without assistance in a general sense on a flat track with no gradient.

19 Class
20 Class
30 Class
36 Class
38 Class
40 Class
41 Class
42 Class
43 Class
44 Class
442 Class
45 Class
47 Class
48 Class
49 Class
53 Class
55 Class
57 Class
58 Class
59 Class
60 Class
80 Class
81 Class
82 Class
90 Class

I hope this is what you want. Tractive effort figures, in lbs, are:

19 Class - 18 140 (original) - 19 440 (Thow round top boiler)
20 Class - 19 440 (original) - 19 240 (Belpaire boiler)
30 Class - 19 116 (original) - 21 424 (super heated)
36 Class - 30 498 (original) - 33 887 (rebuilt)
38 Class - 36 273
40 Class - 49 700
41 Class - 36 700
42 Class - 78 300
43 Class - 42 900
44 Class - 42 900
442 Class - 75 900
45 Class - 74 250
47 Class - 53 800
48 Class - 49 500
49 Class - 44 240
53 Class - 28 780
55 Class - 35 560
57 Class - 56 000
58 Class - 55 000
59 Class - 34 986
60 Class - 59 559 (original) - 63 016 (modified)
80 Class - 80 000
81 Class - 104 000
82 Class - 138 800
90 Class - 139 200

There were some minor disagreements between the two sources on a few of the locos.

Just as an addendum: The tractive effort tells you nothing about how fast a locomotive can pull a load and in fact it falls off, sometimes dramatically, as the speed increases. Some locos (not necessarily any of those in the list) had impressive looking tractive effort figures but were incapable of pulling that load at more than just a few miles per hour.

There is also quite a difference between starting tractive effort and continuous tractive effort. The axle loading of the locomotive affects the tractive effort available. NSWGR working timetables and General Appendix's would give a more realistic figure.

The above list indicates a relatively high tractive effort for the 42 class when compared to the similarly powered 44 class, mainly (I'd suggest) due to the higher axle load available for traction.
