What would you do in case ofbroken rods, pins or guides on eitherengine? A. Handle practically the same as fora similar breakdown on an ordinary slipping and the high pressure was not,the low pressure engine would soon useup all the steam in the receiver, therebystopping the slipping. This will not apply,however, with the American type loco-motive, if the separate exhaust valve wasopen, as in this case the high pressureengine would continue to slip unless thethrottle was eased off or partially \ OK Till-: VVHI£N THE PREUETERMKNICIJ IRKSSfKE IN THE RECEnER PIPE HAS liEEX EXCEEDED.
