Train Whistle Signals

[Anonymous]

WWW.uprr.com has the whistle signals posted.

Years ago, the AAR used to publish booklets about railroads that included the whistle and hand signals, but the only place I have seen this information in the last half century is in railroad Rulebooks. But, the standard signal for a highway rail grade crossing is long - long - short - long held until reaching the crossing. With the use of radios universal, the whistle and hand signals once used between railroaders are seldom used anymore.

Would like to know about the Whistle Signals. How many signals does one hear when approaching a train crossing, how many when approaching a town, etc. Can anyone help?
