I was unaware that 2037’s were everyday locomotives, ....I don’t see one everyday.....yes, it’d be nice to have it repaired properly, and yes, it does deserve to be fixed like factory, however, if the OP wants to run it, it certainly will go as is...as long as it’ll cycle,....if he just wants to run it, does he need to park it till the lever gets fixed?....heck no....if it’ll run ...enjoy it till a repair can be made.......
