    May have to deal with a wagon which has run a 'Hot Box' I seem to remeber being told, that a very temp fix to keep the vehicle mobile, in a very limited way. Is to put some sheet lead between the journal, and the bearing.
    Could anybody confirm this. The idea is to keep the vehicle mobile until, it can be found space for the repairs to be done.
    Thanks in advance

    Assuming that the white metal has run then I would say that the lead idea is a quick fix "to get you home" only. It is only a means of moving something when there is no real alternative & can't be regarded as making the vehicle fit for unsupervised movement in traffic.

    With locos we have found that the application of thick steam oil also helps get you a few more miles in the direction of home.

    A damaged axle journal will be much more difficult to fix than just remetalling & fitting the bearing iteself.

    If the metal has'nt run then a new pad may be enough.

    I have heard of oak bearings being used on vehicles that are used on industrial railways and only moved short distances at low speed. Seems reasonable but I've no experience of this.

    must add that if quenching a hot box with steam oil, pour it onto the box its self, not the joural, else you can alter the chemical make up of the steel, and leads to problems later

    Looks as if the damage is not too bad. So looks as if Armstrong will be getting an order on Monday.
    Bit of a strange failure. The wrong size pad had been fitted. [too small] and the spring had broken allowing the pad to fall away from the journal. I have never seen a pad fail in this way before, has anybody else come across this issue? the pad was quite an old type,but otherwise in fair condition.
    Cheers

    Unless its a matter of life and death, don't quench a hot box period - let it cool naturally.
