Train Weights Question - Posted: January 20, 2020 - 11:43 AM Quote and reply
Can anyone clarify whether the weights shown on current / new trains refer to "UK" tons, or to "Metric" tonnes ? Whilst the difference between them is small (100 Metric tonnes = 98.4 UK tons, it will make a small difference to power calculations.
--------------------------------------
EDITED, 2/2/20.
Typo correction - 100 Metric tonnes was incorrectly shown as 110 Metric tonnes

------------------------------------

For information, and provided I have not miscopied some of the figures (which can be quite small). I have the following weights for some recent trains.
Class 195/0 (2 coaches): 87T
195/1 (3 coaches): 123 T
331/0 (3 coaches): 125.5 T
331/1 (4 coaches): 157.4 T
397 (5 coaches) : 186.0 T

I would assume modern stock is tonnes, not tons.

Note Wikipedia quotes 1 tonne = 0.984207 imperial tons, so much closer than 110 = 98.4, unless that was simply a typo?

From web have seen pic of a 'plate' on Stadler Flirt 755/4 quoted as 163.4 tonnes, with tonnes spelled out in full.

BTW - anyone have the weight of a 755/3?

I have rooted out my conversion tables which say that a tonne = 1000 kg = 0.984 tons = 1.102 short tons = 2205 lbs.
A short ton is 2000 lbs which I think is a US measure.
A ton = 20 cwt = 2240 lbs = 1016 kg

I have it as 135 in my system. Not sure of the decimal component.

Following the previous discussion about train weights, I have compiled some tables showing weights (tonnes and tons) plus power to weight ratios for a range of DMUs - of first & second generation stock. The tables lose formatting if I try to post them here, but if anyone is interested, I can send them copies as Excel files by email. Note that some weights may have changed after refurbishment or changes in seating layout, etc.

A similar table for EMUs is in the early stages of preparation.
