Nissan U20A container restrictions?

[Welshbloke]

I've just bought a pack of these and I'm trying to translate the instructions top left of the sides:

 

コキ100系貨車限定第1積取！限界適用

 

Google Translate app comes up with:

 

First stock of a coke 100 freight car! Marginal application

 

So, does this mean they shouldn't be on anything earlier than a Koki 10*, or they shouldn't be loaded on early Koki 100s? I have them on a Koki 250000 at the moment.

They would be only for use on KoKi 100 variations, ie KoKi 100 through to KoKi 110's, the reason for this is that the deck height are lower on them compared to the KoKi 50000 variations, normally some containers would have marked not for carriage on KoKi 50000's rather than specifying use on KoKi 100 variations. In general the KoKi 100 variations sit at about 1000mm for deck height as opposed to the KoKi 50000's which have a deck height of 1100mm. The only exception to this is the 4 cars of the KoKi 104-10000 sub variant that sit at 1030mm, these cars were built in 1996 for use on trains traversing the Senohachi section of the Sanyo Mainline, they could only carry the stock standard 12 foot containers such as 19D's. The KoKi 104-10000's were fitted with auto uncoupling gear so that the EF67's could detach from the trains whilst in motion, the extra 30mm in height was so they could fit the gear associated with the uncoupling units, they had the auto uncoupling gear removed in March 2002 but they have retained their numbering.

Ah ok, easy enough to swap with the load on a more recent KoKi! As you say, I'd spotted the instruction on other types not to load them on KoKi 50000s but it's just a bit confusing when one type says "do not load on..." while another says "only load on...". They are slightly taller than the normal JRF and private 12' containers.

But the 100mm makes all the difference in tunnels.

 

I've never noticed the 100 only message. And I have the Nissan containers. I'll have to go and have a second look.
