        new npcid = PlayerNPC[playerid];
        if (npcid == INVALID_NPC_ID)
            return SendClientMessage(playerid, 0xFF0000FF, "You are not debugging a NPC.");

        if (!NPC_IsValid(npcid))
            return SendClientMessage(playerid, 0xFF0000FF, "Invalid NPC.");

        new Float:speed = floatstr(cmdtext[15]);

        NPC_SetVehicleTrainSpeed(npcid, speed);
        SendClientMessage(playerid, 0x00FF00FF, "NPC %d train speed set to %.2f", npcid, speed);

        return 1;

## Notes

-   Only works with train vehicles (models 537, 538)
-   Use NPC\_GetVehicleTrainSpeed to check current speed
-   Setting speed to 0 stops the train
